Every machine connected to a network has its own Internet Protocol (IP) address. These addresses help identify devices within the same local area network, or across multiple networks. However, hackers can find your IP address and track what sites you visit and the information you enter online – from your home city to your income and personal health data.

How do I check a valid IP address?

One of the most popular tools is an IP address checker, which allows you to trace a website, email address or domain name to its IP address. These tools also allow you to find the owner, location and ISP of an IP address. They are helpful for tracking spam, viruses, malware and phishing attacks.

NsLookup (also known as NsVerify) is a utility that allows you to query DNS records and determine whether they are correctly configured on servers. This tool is used by IT professionals to troubleshoot connectivity issues, perform network testing and gather data for security analysis.

NsLookup is available for Windows, Mac and Linux. You can use it to look up the current IP address of a device or find the corresponding hostname using a command prompt. You can also track websites and view their IP addresses using a free IP address lookup tool. However, tracing someone’s IP address is only possible if they are currently in an active chat or call with you. This method is not recommended if they are using chat services facilitated by larger platforms, such as Slack or Facebook Messenger, because at least one server is usually between you and the person with whom you are communicating.
