Anonip is a tool to anonymize IP-addresses in log-files. – GitHub
Swiss Privacy Foundation
Anonip is a tool to anonymize IP addresses in log files.
It masks the last bits of IPv4 and IPv6 addresses. That way most of the
relevant information is preserved, while the IP-address does not match a
particular individuum anymore.
Depending on your webserver software, the log entries may directly get piped
to Anonip. The unmasked IP addresses will never be written to any file.
Using shell redirects, it’s also possible to rewrite existing log files.

In the Apache configuration (or the one of a vhost) the log output needs to
get piped to anonip like this:
CustomLog “|/path/to/ [OPTIONS] –output /path/to/log” combined
ErrorLog “|/path/to/ [OPTIONS] –output /path/to/error_log”
That’s it! All the IP addresses will be masked in the log now.
nginx does not support spawning a process it then pipes to. Thus
you need to create a named pipe (file-based FIFO) and start the
processes yourself, along this lines:
mkfifo /path/to/ /path/to/
/path/to/ [OPTIONS] –output /path/to/log < /path/to/ & /path/to/ [OPTIONS] --output /path/to/error_log < /path/to/ & As you can see, you need to start a separate process for each access-log file and for each error-log file. In the nginx configuration (or the one of a vhost) the log output needs to be set to the named pipe like this: access_log /path/to/; error_log /path/to/; As a python module Read from stdin: from anonip import Anonip anonip = Anonip() for line in (): print(line) Manually feed lines: data = ['1. 1. 1', '2. 2. 2', '3. 3. 3'] for line in data: print(ocess_line(line)) Python 2 or 3? For compatibility reasons, anonip uses the shebang #! /usr/bin/env python. This will default to python2 on all Linux distributions except for Arch Linux. The performance of anonip can be improved by running it with python3. If python3 is available on your system, you should preferrably invoke anonip like this: python3 -m anonip [OPTIONS] or python3 /path/to/ [OPTIONS] Motivation In most cases IP addresses are personal data as they refer to individuals (or at least their Internet connection). IP addresses - and the data associated with them - may therefore only be lawfully processed in accordance with the principles of the applicable data protection laws. Storage of log files from web servers, for example, is only permitted within close time limits or with the voluntary consent of the persons concerned (as long as the information about the IP address is linkable to a person). Anonip tries to avoid exactly that, but without losing the benefit of those log files. With the masking of the last bits of IP addresses, we're still able to distinguish the log entries up to a certain degree. Compared to the entire removal of the IP-adresses, we're still able to make a rough geolocating as well as a reverse DNS lookup. But the otherwise distinct IP addresses do not match a particular individuum anymore.

How do I Hide My IP Address? – Avast
What is an IP address, anyway?
An IP address is a series of numbers that identifies your device or network on the internet. Activity on the internet is a series of two-way communications between clients — software, such as a web browser, that requests data — and servers, which reply to clients with responses. Every client has an IP address that tells servers who is making the request.
So, it’s easy to understand what an IP address is and also why they’re important. IP addresses let search engines like Google know where to send the results of a search, help websites know who’s visiting their site, and make sure you receive the emails that are addressed to you.
In other words, IP addresses undergird how the internet works in general. Thankfully, it’s very easy to find your IP address if you need this information.
Three ways to hide your IP
Now, let’s take a look at three tools you can use to hide your IP address. Each offers its own blend of privacy, security, and practicality.
1. Use a VPN
A VPN is an intermediary server that encrypts your connection to the internet — and it also hides your IP address. A VPN encrypts all your traffic, not only in your browser but also in other apps, and then passes traffic onward to its destination. They’re a popular privacy solution, and as such, there’s a strong incentive for VPN providers to design tools that are as easy to use as they are secure.
Here’s how to hide your IP address with a VPN: Simply download a VPN such as Avast SecureLine VPN, log in, and turn it on to protect both your IP address and your internet traffic.
How does a VPN hide your IP address?
When you’re using a VPN, your IP address is hidden because your traffic takes a detour through the VPN server. When your traffic — sites visited, online apps used, uploads, downloads, etc. — reaches its destination, it does so under a “virtual” IP address assigned by the VPN.
There’s only one party who’ll be able to see your actual IP address: your VPN provider. That’s why you should choose a trusted VPN provider that isn’t going to keep logs on your activity.
Avast SecureLine VPN is a safe, secure, and convenient way to mask your IP address. It’ll hide your online activity from your internet service provider (ISP), employer, school, and anyone else on your network, including a snooping cybercriminal. And we never keep any logs on sites you visit, apps you use, or content you view.
2. Use Tor
Comprising thousands of volunteer-run server nodes, Tor is a free network that conceals your identity online via multiple layers of encryption. When you access Tor, typically by using the free Tor Browser, your traffic is relayed and encrypted through a series of three relay nodes, each of which decrypts one layer of encryption to learn the identity of the next node. When your traffic leaves the final node, it’s fully decrypted and sent to its destination.
The relay system hides your IP address, but not without cost: because Tor’s encryption system is so thorough, it takes a long time for your traffic to complete its journey. You’ll be sacrificing browsing speed for Tor’s anonymity. This is a worthwhile tradeoff when it really counts, such as for whistleblowers and political dissidents. But if you’re simply seeking to hide your IP address, when comparing Tor and a VPN, you’ll find a VPN to be a far more convenient and faster solution.
How does Tor hide your IP address?
When you use Tor, each relay node along your traffic’s pathway through the Tor network knows only the IP address of the node immediately before and after it. Even if an attacker manages to intercept your traffic while it travels from the final node to your destination server, it’d be very difficult at that point to parse your original IP address.
3. Use a proxy
A proxy server handles your internet traffic on your behalf. A proxy sits in front of a client or network of clients, forwarding requests while also receiving and delivering responses from servers. You may need to manually adjust your device’s proxy settings if you want to use a proxy.
Unlike a VPN, most proxies won’t encrypt your traffic, and they also won’t hide your IP address from anyone who can intercept your traffic on its way from your device to the proxy. Proxy servers, especially free web-based proxies, tend to be less reliable than VPNs. That’s why proxies are best used as a quick, temporary solution as opposed to a long-term privacy plan.
How does a proxy hide your IP address?
Some proxy servers can mask your IP address with a fake one. You’ll appear as though you’re based in the same country as your proxy server. If you’re using a proxy to hide your IP, be aware that not all proxies offer equal protection.
Transparent proxies conceal neither your IP address nor your use of a proxy.
Anonymous proxies hide your IP address but not your use of a proxy.
High anonymity (or elite) proxies hide both your IP address as well as your use of a proxy.
Some sites or content platforms may block traffic from known proxies, so you’ll have to be careful if you’re trying to use a proxy to access media.
Why should I hide my IP address?
Your IP address identifies you online, and in today’s data-driven world, your online activity is very valuable. It’s important to hide your IP address so that you can regain control over your privacy while you’re online. Among other sensitive info, your IP can reveal your shopping and buying habits as well as your physical location. So why hide your IP? You’ve got plenty to gain, and not much to lose.
Hide your IP to browse anonymously
Advertisers and marketers can track you across the internet and analyze your browsing habits with the goal of marketing to you more effectively. Unfortunately, even hiding your IP address won’t stop them, because tracking cookies also deliver this information — which is why you should regularly take the time to delete cookies from your browser.
To take private internet browsing to the next level, consider a dedicated private browser like Avast Secure Browser. It includes a range of advanced anti-tracking features to let you use the internet without leaving any clues behind that companies and individuals can use to follow your activity.
Hide your IP to shield your location
Hide your IP address behind another IP in a different part of the world and no one will know where you really are. This includes websites and services that host geo-restricted content. For example, if you’re traveling abroad and want to access movies or TV shows that are available only for your home country, you can use a VPN or proxy to unblock that website with a false IP address in the correct location.
Many IP addresses are linked to a real-world address, or at least to a general location. If you’re frequently using false IP addresses to change your online location, no one will be able to figure out where you actually are.
Can my IP address ever truly be hidden?
While it’s not possible to hide your IP address from everyone, you can achieve an effective level of privacy sufficient for everyday needs. With a VPN, the only entity that can link your online activity to your IP address is your VPN provider itself. This is why it’s so important to choose a VPN provider with a reliable reputation for security, and one that doesn’t keep logs of user activity.
Your ISP can see the type, timing, and amount of traffic you’re sending to the VPN server, but they won’t know the specifics. The same goes for Tor. Many proxies don’t encrypt your traffic, and so your ISP will be able to access your activity if it wants to while you’re using a proxy. And, as mentioned earlier, all the websites and services you use while connected to a VPN will see only the VPN’s IP address, not yours.
The primary purpose for hiding your IP address is to protect your online activity and location from third-party observers: websites, advertisers who use ad tracking techniques, and cybercriminals. When your safety and privacy is at risk, it’s important to be proactive.
What is IP masking?
IP masking is the technique of concealing your IP address by adopting a false one. This is how hiding your IP address works — they’re two ways to refer to the same thing. If you’re interested in learning how to mask your IP address, you can apply the same techniques described in this article. After all, the only way to hide your IP address and still use the internet is to mask it behind another one.
Your traffic is always going to need an IP address online, since that’s how websites and services know who’s making the requests and where to send the replies. Clients use IP addresses to reach servers, and servers use IP addresses to send requested data back to the correct client.
That request-and-response system is part of the TCP/IP model, which governs how devices on the internet communicate with one each another. IP addresses are classified in a variety of ways: IPv4 vs. IPv6, public vs. local, and static vs. dynamic IP addresses. Read more about IP addresses here.

Proxy Basics. 5 Things You Know Before You Use One – What Is My IP …
One of the most misunderstood computer terms—and services—may be the proxy. Most of us aren’t IT experts or computer geeks, so all we want to know is “What does it do for me? ” So let’s try to answer that question as simply as we can.
You may have even used a proxy, but just not have been aware of it. Today, a common type of proxy is called a VPN, for “virtual private network. ”
If you look up the word proxy, you’ll see that it simply means a “substitute who stands in for or represents another. ” In the Internet world, a proxy is an IP address that you can use as you go on the Internet that also shields your actual IP address at that time.
You either have to sign up for a virtual private network or be given access to one, by your employer, for example.
A VPN is more than just a substitute IP address—it also provides a highly secure connection that delivers more security that most on the Internet, including the one offered by your Internet Service Provider.
A VPN is a connection that’s available online, on-demand. Once you sign up for a VPN account—whenever you want anonymity, a safer secure connection or a way around Internet blocks on your IP address—you can route your connection through your VPN provider.
You get to keep your current ISP, which remains your primary Internet connection at home. There are some free VPNs, but it’s better if you pay for better service.
There are two different types of VPNs that are common today. One is for private/corporate work purposes and the other is for Internet browsing only.
A VPN for work purposes.
For example, my wife works for an advertising agency as a proofreader. At times, she’s asked to do work on the computer long after she’s left work. But she no longer has to go back to the office to do her work, thanks to the company’s very own virtual private network.
Instead of going into the office, she simply goes to her work laptop in our home office. We have an Internet connection that is always running. She doesn’t have to open an Internet browser, such as Google Chrome or Internet Explorer—she simply clicks on an icon and keys in her password to open up the VPN automatically.
Once she’s on, she can access drives and folders on her company’s server, which are accessible only to employees who are on-site or who have the exclusive VPN connection. That way, she can open up a presentation or a document that she’d typically be able to open only at work. That whole time she’s online and connected to her workplace computer/server, she’s using a virtual private network.
A secure connection is what is important.
This VPN connection provides her with a data “tunnel” which all of her online activity will go through. This is the first and most well-known quality of a VPN. All data “traffic” that goes through a VPN, whether it’s an email or a Google search, is encrypted—that means it’s electronically “scrambled” and would be undecipherable if tapped into by a hacker.
A VPN for ordinary folks.
As you might know, a lot of people have become worried about Internet safety and privacy. Many of these same people are worried that their IP addresses might be captured by “outsiders” or hackers and used for scams or computer attacks.
Thankfully, there are VPNs that are dedicated to the one application (program) that people care about the most: Internet browsing. Instead of a corporate virtual private network to connect to the workplace, a public VPN lets you connect to a network of computers to hide your IP address and give you a secure connection on the Internet while protecting all of your data transmissions.
To recap: People don’t use VPNs just to hide their IP addresses. A VPN can also protect your data when you’re on the Internet and can give you access to the websites and information that might otherwise block you out.
