Proxy Server – What They Are & How to Use – What Is My IP …

Learn what a proxy is and the risks involved.
You may not know it (and once you do not know it, it may not bother you), but every time you reach out to a website or connect with anyone online, your online connection gives your computer “address” to the site/person you’re connecting with.
Why? So that you the other end knows how to send information (a Web page, email, etc. ) back to your computer…to you. That address is your public IP address. IP stands for Internet Protocol. Want to see yours right now? Just go here to our home page and it will be there.
Without an IP address, you wouldn’t be able to do any Internet/online activity and others online wouldn’t be able to reach you. It is how you connect to the world.
Where does your IP address come from?
You can thank your Internet Service Provider (AT&T, Comcast, Verizon, etc. ) for your IP address at home, as well as for your Internet connection. Your smart device also uses an IP address when you’re browsing the web or using an app.
Most people are completely happy with how all of that works.
But there are few realities about public IP addresses that does bother some people:
Your IP address identifies where you are in the world, sometimes to the street level.
It can be used by websites to block you from accessing their content.
It ultimately ties your name and home address to your IP address, because someone is paying for an Internet connection at a specific location.
But there are a few ways you can get around those realities, and one them is to use a proxy service or proxy server (people simply say “proxy. ”)
Proxy means “substitute. ”
A proxy lets you go online under a different IP address identity.
You don’t change your Internet provider; you simple go online and search for “free proxies” or “list of proxies” and you will get several websites that provide lists of free proxies.
It’s really that simple to find proxies, just like you order shoes, movies and airline tickets online. However, it isn’t so simple to figure out how to use one without some guidance. For more help and information on proxies, visit our Learning Center.
How a proxy operates.
A proxy server is a computer on the web that redirects your web browsing activity. Here’s what that means.
Normally, when you type in a website name ( or any other), your Internet Service Provider (ISP) makes the request for you and connects you with the destination—and reveals your real IP address, as mentioned before.
When you use a proxy your online requests get rerouted.
While using a proxy, your Internet request goes from your computer to your ISP as usual, but then gets sent to the proxy server, and then to the website/destination. Along the way, the proxy uses the IP address you chose in your setup, masking your real IP address.
Why you might want to use a proxy.
Here why some people turn to using a proxy—and why you might be interested as well.
A school or local library blocks access to certain websites and a student wants to get around that.
You want to look at something online that interests you…but you would prefer it couldn’t be traced back to your IP address and your location.
You’re traveling abroad and the technology set up in the country you’re in prevents you from connecting to a website back home.
You want to post comments on websites but you do not want your IP address to be identified or your identity tracked down.
Your employer blocks access to social media or other sites and you’d like to bypass those restrictions.
Why you might not want to use one
You should keep in mind that your employer, your ISP and other networks might object to your using a proxy. Just because you can do it, doesn’t mean you should. And in some cases, websites will blacklist IP addresses they suspect or know are from a proxy.
Not all proxies are alike.
Even though all proxies help you access websites you might not otherwise get to, not all proxies behave the same way. A proxy can fall into one of four categories:
Transparent proxy. It tells websites that it is a proxy server and it will pass along your IP address anyway.
Anonymous proxy. It will identify itself as a proxy, but it won’t pass your IP address to the website.
Distorting proxy. It passes along an incorrect IP address for you, while identifying itself as a proxy.
High Anonymity proxy. The proxy and your IP address stay a secret. The website just sees a random IP address connecting to it…that isn’t yours.
As mentioned before, you can find proxy servers easily for free; but as with any free service, you should be aware of the risks involved, because a free proxy may not be as safe or secure as you hope it would be. That being said, here’s an article you should read: Anonymous Proxy Risks
As with anything else you do online, be sure to do some homework first.

Is using a proxy server legal?

Yes, it is legal to use a proxy server. Proxies have many different uses, including enabling remote work; setting up a support system for users who are located outside a particular network; protecting networks and Internet users from malicious content; streaming online content from outside a country and more.
When are Proxy Servers Illegal?
Keep in mind that there are some circumstances in which using a proxy server is illegal. For example, some websites stream content that is only available to audiences who have paid their license fees to access it. If you did not pay license fees and tried to access that content via a proxy server, that act would be considered illegal.
Why Use a Proxy Server?
Let’s say you are living in the United Kingdom, and trying to log onto a U. S. based website to watch educational documentaries or your favorite TV programme. However, you discovered that IP addresses in the UK have been blocked. Don’t feel down just yet because proxies allow you to circumvent web filters that are blocking you from your geographical location.
There is content out there that may have been produced for individuals to view for free, so why shouldn’t you be able to view or access it? As long as using proxies do not appear to be an infringement of copyright law, you can use proxies to stream content while enjoying complete peace of mind.
Good Practices for Using Proxies Legally
Before you use a proxy server to stream any content that has been blocked in your geographical location, you should carefully read the target website’s terms and conditions. This practice ensures you avoid breaking any terms and conditions that may lead the target website to take legal action against you.

What is a Proxy Server and How Does it Work? – Varonis

The actual nuts and bolts of how the internet works are not something people often stop to consider. The problem with that is the inherent danger of data security breaches and identity theft that come along with the cute dog pictures, 24-hour news updates, and great deals online.
But what actually happens when you browse the web? You might be using a proxy server at your office, on a Virtual Private Network (VPN) or you could be one of the more tech-savvy who always use a proxy server of some kind or another.

“It’s a new world of remote work and this was a jumpstart on securing it. ”
What’s a Proxy Server?
A proxy server is any machine that translates traffic between networks or protocols. It’s an intermediary server separating end-user clients from the destinations that they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy.
If you’re using a proxy server, traffic flows through the proxy server on its way to the address you requested. The request then comes back through that same proxy server (there are exceptions to this rule), and then the proxy server forwards the data received from the website to you.
If that’s all it does, why bother with a proxy server? Why not just go straight from to the website and back?
Modern proxy servers do much more than forward web requests, all in the name of data security and network performance. Proxy servers act as a firewall and web filter, provide shared network connections, and cache data to speed up common requests. A good proxy server keeps users and the internal network protected from the bad stuff that lives out in the wild internet. Lastly, proxy servers can provide a high level of privacy.
How Does a Proxy Server Operate?
Every computer on the internet needs to have a unique Internet Protocol (IP) Address. Think of this IP address as your computer’s street address. Just as the post office knows to deliver your mail to your street address, the internet knows how to send the correct data to the correct computer by the IP address.
A proxy server is basically a computer on the internet with its own IP address that your computer knows. When you send a web request, your request goes to the proxy server first. The proxy server then makes your web request on your behalf, collects the response from the web server, and forwards you the web page data so you can see the page in your browser.
When the proxy server forwards your web requests, it can make changes to the data you send and still get you the information that you expect to see. A proxy server can change your IP address, so the web server doesn’t know exactly where you are in the world. It can encrypt your data, so your data is unreadable in transit. And lastly, a proxy server can block access to certain web pages, based on IP address.
What are Forward Proxies
A forward proxy server sits between the client and an external network. It evaluates the outbound requests and takes action on them before relaying that request to the external resource.
Most proxy services that you’re likely to encounter are forward proxies. Virtual Private Networks and Web content filters are both examples of forward proxies.
What are Reverse Proxies
A reverse proxy server sits between a network and multiple other internal resources. A large website might have dozens of servers that collectively serve requests from a single domain. To accomplish that, client requests would resolve to a machine that would act as a load balancer. The load balancer would then proxy that traffic back to the individual servers.
Some popular open source reverse proxies are:
Varnish
Squid
Why Should You Use a Proxy Server?
There are several reasons organizations and individuals use a proxy server.
To control internet usage of employees and children: Organizations and parents set up proxy servers to control and monitor how their employees or kids use the internet. Most organizations don’t want you looking at specific websites on company time, and they can configure the proxy server to deny access to specific sites, instead redirecting you with a nice note asking you to refrain from looking at said sites on the company network. They can also monitor and log all web requests, so even though they might not block the site, they know how much time you spend cyberloafing.
Bandwidth savings and improved speeds: Organizations can also get better overall network performance with a good proxy server. Proxy servers can cache (save a copy of the website locally) popular websites – so when you ask for, the proxy server will check to see if it has the most recent copy of the site, and then send you the saved copy. What this means is that when hundreds of people hit at the same time from the same proxy server, the proxy server only sends one request to This saves bandwidth for the company and improves the network performance.
Privacy benefits: Individuals and organizations alike use proxy servers to browse the internet more privately. Some proxy servers will change the IP address and other identifying information the web request contains. This means the destination server doesn’t know who actually made the original request, which helps keeps your personal information and browsing habits more private.
Improved security: Proxy servers provide security benefits on top of the privacy benefits. You can configure your proxy server to encrypt your web requests to keep prying eyes from reading your transactions. You can also prevent known malware sites from any access through the proxy server. Additionally, organizations can couple their proxy server with a Virtual Private Network (VPN), so remote users always access the internet through the company proxy. A VPN is a direct connection to the company network that companies provide to external or remote users. By using a VPN, the company can control and verify that their users have access to the resources (email, internal data) they need, while also providing a secure connection for the user to protect the company data.
Get access to blocked resources: Proxy servers allow users to circumvent content restrictions imposed by companies or governments. Is the local sportsball team’s game blacked out online? Log into a proxy server on the other side of the country and watch from there. The proxy server makes it look like you are in California, but you actually live in North Carolina. Several governments around the world closely monitor and restrict access to the internet, and proxy servers offer their citizens access to an uncensored internet.
Now that you have an idea about why organizations and individuals use a proxy server, take a look at the risks below.
Proxy Server Risks
You do need to be cautious when you choose a proxy server: a few common risks can negate any of the potential benefits:
Free proxy server risks
You know the old saying “you get what you pay for? ” Well, using one of the many free proxy server services can be quite risky, even the services using ad-based revenue models.
Free usually means they aren’t investing heavily in backend hardware or encryption. You’ll likely see performance issues and potential data security issues. If you ever find a completely “free” proxy server, tread very carefully. Some of those are just looking to steal your credit card numbers.
Browsing history log
The proxy server has your original IP address and web request information possibly unencrypted, saved locally. Make sure to check if your proxy server logs and saves that data – and what kind of retention or law enforcement cooperation policies they follow.
If you expect to use a proxy server for privacy, but the vendor is just logging and selling your data you might not be receiving the expected value for the service.
No encryption
If you use a proxy server without encryption, you might as well not use a proxy server. No encryption means you are sending your requests as plain text. Anyone who is listening will be able to pull usernames and passwords and account information really easily. Make sure whatever proxy server you use provides full encryption capability.
Types of Proxy Servers
Not all proxy servers work the same way. It’s important to understand exactly what functionality you’re getting from the proxy server, and ensure that the proxy server meets your use case.
Transparent Proxy
A transparent proxy tells websites that it is a proxy server and it will still pass along your IP address, identifying you to the web server. Businesses, public libraries, and schools often use transparent proxies for content filtering: they’re easy to set up both client and server side.
Anonymous Proxy
An anonymous proxy will identify itself as a proxy, but it won’t pass your IP address to the website – this helps prevent identity theft and keep your browsing habits private. They can also prevent a website from serving you targeted marketing content based on your location. For example, if knows you live in Raleigh, NC, they will show you news stories they feel are relevant to Raleigh, NC. Browsing anonymously will prevent a website from using some ad targeting techniques, but is not a 100% guarantee.
Distorting proxy
A distorting proxy server passes along a false IP address for you while identifying itself as a proxy. This serves similar purposes as the anonymous proxy, but by passing a false IP address, you can appear to be from a different location to get around content restrictions.
High Anonymity proxy
High Anonymity proxy servers periodically change the IP address they present to the web server, making it very difficult to keep track of what traffic belongs to who. High anonymity proxies, like the TOR Network, is the most private and secure way to read the internet.
Proxy servers are a hot item in the news these days with the controversies around Net Neutrality and censorship. By removing net neutrality protections in the United States, Internet Service Providers (ISP) are now able to control your bandwidth and internet traffic. ISPs can potentially tell you what sites you can and cannot see. While there’s a great amount of uncertainty around what is going to happen with Net Neutrality, it’s possible that proxy servers will provide some ability to work around an ISPs restrictions.
Varonis analyzes data from proxy servers to protect you from data breaches and cyber attacks. The addition of proxy data gives more context to better analyze user behavior trends for abnormalities. You can get an alert on that suspicious activity with actionable intelligence to investigate and deal with the incident.
For example, a user accessing GDPR data might not be significant on its own. But if they access GDPR data and then try to upload it to an external website, it could be an exfiltration attempt and potential data breach. Without the context provided by file system monitoring, proxy monitoring, and Varonis threat models, you might see these events in a vacuum and not realize you need to prevent a data breach.
