IP Address Lookup


The information shown on the What Is My IP homepage about IP address location is not as detailed as what you’ll find using the IP address lookup tool.

IP Address Lookup

An IP address lookup will determine the location of any IP address. The results have quite a bit of information.  The results include information like the city, state/region, postal/zip code, country name, ISP, and time zone. Consequently, this data is used by various agencies to find the owner of an IPv4 or IPv6 address.

IP Address Location Accuracy

It's important to understand that no IP Lookup tool is 100% accurate due to many different factors. One of those factors include where the owner of the IP has it registered. Other factors are where the agency that controls the IP is located, proxies, cellular IPs, etc.

For example, if you are in the US and the controlling agency of the IP is located in Canada, the lookup data may show Canada as the IP location. Showing a Canadian IP while in the northern US is not uncommon for mobile users.

IP lookup results are shown from several different IP location databases. Therefore, you can see how each database may report differently. It is especially relevant to reiterate the less than 100% accuracy of these databases.

IP Address Results

Users often think they are going to find the exact IP location of someone. This is simply not true. To clarify, we are not aware of any IP location database that will give you the exact physical address of the IP address you lookup. At best, you'll get the exact city in which the user of the IP is located.

Only the Internet Service Provider of the IP address in question can provide an exact physical address. Internet Service Providers usually have logs of which user was assigned an IP at any given time. There are likely limits as to how long an ISP would store these records. However, without a police warrant, or some sort of legal document, the ISP is unlikely to turn over any information.

Don't expect the ISP to give you the mailing address of the user that received the assignment of the IP at the time you received the offensive email / questionable communication from said IP address. Turn over the communications to the authorities and let them do their job.

Update Your IP Location

If you find that your IP location information is incorrect, you can always reach out to any of our providers and update your IP address location if you'd like.


In conclusion, if someone has sent an offensive or harassing communication, the best you can do is to file a complaint with the ISP and forward them all of the information from the questionable / offensive communication regarding the complaint.
