Where Is This IP From?

Enter IP-address:

From time-to-time, you may need to know an IP-address location. There are actually several ways to get geolocation data for an IP-address. Depending on your goals, you may choose how to do that. First way is to use who is IP lookup tool, another one is to use geoip tool.

Despite the way you choose, here is what you need to understand. All techniques for IP geolocation are based on the data, which are edited by Internet Service Providers, when they obtain IP-address ranges (networks) from Regional Internet Registries. It means that IP location could be as precise as it was stated by ISP, which maintains this IP-address. Another one is that IP location is usually a location of ISP organization.

There is no direct association of an IP-address and geographical coordinates. All existing associations in the world are indirect and not 100% accurate.

And the last point to understand is that, in the best case, you may get the location by IP with maximum precision to city level, in many cases to country-level only. If you need to know why, read this article.

1. Lookup IP WHOIS Data

This is the best way to go if you're looking for most accurate and actual IP-address information. As far as it is a source data for any other IP geolocation tools. To do that, you may use our IP whois tool, which is a centralized service to request data about any IP-address across all existing RIRs. In other way, you may need to visit each RIR website, or may use referral whois command-line tools.

It is really the best way for manual research of IP location data.

2. Lookup With Geo-IP Tool

Anyway, whois information does not contain anything else except country, city and address of ISP organization to which a given IP-address belongs to. Geo-IP tools just automatically process whois data and associate it with such entities like geographical coordinates, time-zones or some other useful data. As far as to build such database there is required to process a lot of data (billions of IP-address blocks for both IPv4 and IPv6), such databases are like cached snapshots of whois data. It means that such databases could be a bit out-of-date. Also, due to many factors, there is not always possible to process all whois data correctly by automated algorithms, so for some IP ranges some data could be missing or contains some errors.

But the big benefit of such databases is their significantly better performance for automated queries then whois requests. Plus them could provide a better data representation. For example, our geo-IP service provides an API, which handles millions of queries per day for different third-party websites.

So, even for manual research you can start with geographical IP location lookup, then just to make sure data is correct, make whois search.
