Find the IP address of another networked computer in Windows
This content has been archived, and is no longer maintained by Indiana University. Information here may no longer be accurate, and links may no longer be available or reliable.
Using the fully qualified domain name (FQDN) of a networked computer, nslookup will query a DNS server and return the IP address that corresponds to that domain name.
In Windows 10 and earlier, to find the IP address of another computer:
Open a command prompt.
Type nslookup plus the domain name of the computer you want to look up, and press Enter. For example, to find the IP address for, you would type:
nslookup
This command will return the following information:
Server:
Address: 129. 79. 1. 1
Name:
Address: 129. 61
The first two lines show the domain name and IP address of the DNS server that answered the nslookup query. The next two lines show the domain name and IP address of the computer for which you were searching.
When you’re finished, type exit and press
Enter to return to Windows.

Get User IP Address in PHP | Delft Stack
HowToPHP HowtosGet User IP Address in PHPCreated: April-03, 2021 | Updated: May-12, 2021Use $_SERVER[‘REMOTE_ADDR’] to Find the User’s IP Address in PHPUse $_SERVER[‘REMOTE_ADDR’], $_SERVER[‘HTTP_CLIENT_IP’] and $_SERVER[‘HTTP_X_FORWARDED_FOR’]to Find the User’s IP AddressUse Ternary Operator and isset() Function to Find the User’s IP AddressWe will introduce a way to access the user’s IP address from a server in PHP using the $_SERVER super global variable with REMOTE_ADDR as the only array element. It is used as $_SERVER[‘REMOTE_ADDR’] will demonstrate another way to access the user’s IP address in PHP using the conditional expression to check whether the user’s IP addresses come from shared internet, from a proxy, or is the real IP address. This method uses array elements like HTTP_CLIENT_IP, HTTP_X_FORWARDED_FOR and will show you a short-hand method to get the user’s IP address in PHP using the ternary operator and isset() function. This method also uses the array elements like HTTP_CLIENT_IP, HTTP_X_FORWARDED_FOR and REMOTE_ADDR in the $_SERVER super global $_SERVER[‘REMOTE_ADDR’] to Find the User’s IP Address in PHPWe can use the $_SERVER[‘REMOTE_ADDR’] expression to find the IP address from where the user is accessing the current page. $_SERVER is the super global variable in PHP, and it takes a variety of array elements as arguments. We use the REMOTE_ADDR as the array element in $_SERVER variable to access the client’s actual IP address. Note that $_SERVER[‘REMOTE_ADDR’] does not always give the correct IP address of the client in all cases. We will discuss the other cases below. Ensure your Server API(SAPI) is well-configured so that the above expression will return the real IP of the the example below, the localhost is used as the server. Thus, it returns the loopback IP address. To learn about the loopback address, please refer here. Suppose the URL of the following PHP script is localhost/ It outputs the IP address of the local machine as::1. ::1 is the IPv6 representation of the example, assign the $_SERVER[‘REMOTE_ADDR’] to a variable ip_addr. Then, print the variable using the echo. Example Code:# php 7. x
Output:The user’s IP address is -::1
Use $_SERVER[‘REMOTE_ADDR’], $_SERVER[‘HTTP_CLIENT_IP’] and $_SERVER[‘HTTP_X_FORWARDED_FOR’]to Find the User’s IP AddressWe can use the array elements of the superglobal variable $_SERVER like $_SERVER[‘REMOTE_ADDR’], $_SERVER[‘HTTP_CLIENT_IP’] and $_SERVER[‘HTTP_X_FORWARDED_FOR’] to find the IP address of the user in PHP. Use$_SERVER[‘REMOTE_ADDR’] to find the real IP address of the user. Use $_SERVER[‘HTTP_CLIENT_IP’] to find the IP address when the user is accessing the page from shared internet. Use $_SERVER[‘HTTP_X_FORWARDED_FOR’] to find the IP address when the user uses a proxy to access the webpage. Note that headers like HTTP_X_FORWARDED_FOR and HTTP_CLIENT_IP can be spoofed as this can be set by anyone. Sometimes, they may not represent the real IP address of the Example, use the empty() function to check whether the $_SERVER[‘HTTP_CLIENT_IP’] contains something. If it contains, assign the vale in the $ip variable and print i.
Again, perform a check on $_SERVER[‘HTTP_X_FORWARDED_FOR’] accordingly and assign the value and print it if it exists. Perform similar operation on $_SERVER[‘REMOTE_ADDR’] example below, $_SERVER[‘REMOTE_ADDR’] returns the IP address as the user is not using any proxies or shared internet connection. Check the PHP Manual to know more about the $_SERVER array. Example Code:#php 7. x
Output:::1
Use Ternary Operator and isset() Function to Find the User’s IP AddressWe can use a short-hand method to find the user’s IP address in PHP using the ternary operator. In this method, the isset() method checks whether the array contains the specified elements or the header example, use the isset() function to check whether the array contains HTTP_CLIENT_IP. If the condition is true, HTTP_CLIENT_IP is set. Then, If the condition fails, isset() function is used to check whether the array contains HTTP_X_FORWARDED_FOR. Similarly, if the condition is true, HTTP_X_FORWARDED_FOR is set, and REMOTE_ADDR is set when the condition the example below, the client is not using a proxy or a shared internet. Therefore, the $_SERVER[‘REMOTE_ADDR’] gets executed. Please check the MSDN Web Docs to know about the ternary operator. x
$ip = isset($_SERVER[‘HTTP_CLIENT_IP’])? $_SERVER[‘HTTP_CLIENT_IP’]: isset($_SERVER[‘HTTP_X_FORWARDED_FOR’])? $_SERVER[‘HTTP_X_FORWARDED_FOR’]: $_SERVER[‘REMOTE_ADDR’];
echo “The user IP Address is – “. $ip;? >
Output:The user IP Address is -::1

Can I Be Tracked by my IP Address – WhatIsMyIP.com®
Is it feasible to track my IP address if known by others?
Someone has my IP address, can they find me?
When you connect to the internet through your Internet Service Provider(ISP), they assign an IP address. Your IP address is similar to your mailing address, but for your computer, on the internet. While the IP address used to route internet traffic to your computer it does not reveal your location. If someone was able to get your IP address they could learn a bit about your internet service, such as which provider you use to connect to the internet, but they really can’t locate you, your home, or your office.
In some circumstances they may locate the city you are in, or perhaps a nearby city, but they will not have your physical address. Once they trace you back to your ISP they will lose your trail. While strangers may not be able to find you, your ISP knows where you are. ISPs will generally go to great lengths to protect you and your privacy but they do keep logs of your connections.
One big exception involving law enforcement. If you were to participate in illegal activities then a law enforcement agency can get a court order and submit it to your ISP to request your information. Obviously, easily finding you with law enforcement involved.
In the end, the simple answer is no, that you are unable to track my IP address. If someone was to get your IP address they can not find you. There are other ways you can be located but this isn’t one of them. Posting your name and town online via social media, more likely tracked, than by your IP address.
