What is IP Lookup and How to Use It?

IP Lookup is a networking tool designed to help you extract important information related to an IP address. This tool is suitable for network professionals or administrators who wants to check a suspicious IP in their network. The IP Lookup tool provides information like Geolocation, regions, ownership information and a lot more which can be helpful in detecting an unknown intruder in the network.

How Does IP Lookup work?

IP Lookup performs a reverse DNS lookup to figure out the information related to the IP address. Reverse DNS, if you don’t know already, is a technique used in networking to extract the domain name or hostname from an IP address. It is called reverse DNS because it is the opposite of what a DNS does, which is to locate the IP address related to a domain name or hostname.

So, you will give IP Lookup the IP Address of the targeted device/user and IP Lookup will perform a reverse DNS to find the Hostname and a lot of other information. The information found by IP Lookup will be shown on your screen. You can then use the extracted information for whatever reason you want.

Why would I need IP Lookup?

Security: IP Lookup can be useful to detect intruders and malicious activities in your network. Since IP Lookup provides geolocation and owner details, you can use this to locate a suspicious entry in your network. There are cases where there’s an IP address trying to get through your firewall and information provided by the IP Lookup tool can be useful in determining whether you should be worried or not.

Check Unknown IP Addresses: You can also use the IP Lookup to check the information of an unknown user. This is useful in situations where you are notified of an unknown login or login attempt. This is even useful for a person who isn’t an IT professional. For example, if you open your Facebook account and look at the current or past sessions, you can see the IP addresses that were used to sign in to your account. If you see a suspicious IP address in that list, you can use the IP Lookup tool to know more details about that login IP Address. This will help you figure out who accessed your Facebook account. These features are available on almost all of the major platforms including Gmail so IP Lookup can be pretty useful.

Network Troubleshooting: IP Lookup is also useful for troubleshooting slow networks as well. Use the IP Lookup tool to check the source of the traffic which will help you figure out the source of bottleneck. This is because a lot of the times a certain person might just be downloading or streaming which might the reason be behind slow internet. This will help you to determine whether there is a problem in the network or just because of the heavy bandwidth usage.
