Top 5 Free Online IP Lookup Tools

There is no shortage of IP tracking tools. For convenience, we’ll focus on the 5 best IP lookup tools.

  1. SpiceWorks IP Lookup

This client offers a number of IP-based services, including an easy-to-use IP lookup tool offering information about the ISP domain and whereabouts. It also hosts other tools and guides like IP blacklist checking, subnet, calculator, and even a map with the lookup tool.

A key drawback of this tool, however, is the lack of IPv6 support, which cannot be ignored given the decline of IPv4 infrastructure.

  1. iplocation.ioEditor’s Choice

This IP host features a broader range of IP tools including address compression and expansion, reverse lookups, and several address conversion and generation resources. It also provides developer, DNS, SEO, and cybersecurity services, among others.

Its flagship capability, however, is IP address tracking, which is available on the home page. When you visit the website, the first thing it displays is your own IP address, even specifying whether it is IPv4 or IPv6, indicating support for both versions.

What makes this tool the ideal choice for IP checking is its access to multiple IP address databases and proprietary geolocation APIs, which allows it to provide geotracking details through multiple hosts which you can compare when authenticating results. It even supports each set of results with a visual map, which you can click on to see the bigger picture.

And the best part, this website provides its service absolutely free of charge with need for an account whatsoever.

  1. WhatIsMyIPAddress.com

Among IP lookup sites, this server experiences an immense amount of traffic for users. While that might be largely due to its search-friendly title, it’s safe to say that its actual IP lookup capabilities are no joke.

On top of offering full IPv4 and IPv6 support, this website also offers security checks. Its IP address tracking tool is simple to use, provides suitable results, and even offers a distinction between static and dynamic IPs.

The ability to locate the exact country, along with city identification with more than 80% precision, certainly raises the bar high for geolocation. Notably, rather than using Google Maps, this tool uses the open-source client LeafLet to generate its maps.

  1. IP Location with Small SEO Tools

Small SEO Tools is well-known for its plethora of web tools and helpful resources. Its IP location checker is straightforward and provides all the necessary information for lookup queries. However, the lack of IPv6 support when that is expected to be the dominant address type for devices everywhere is a potential deal-breaker.

Also, it has no dedicated blacklist checks. The one it has worked for domains. However, it can still be used to assess the status of IPs by simply adding the “https://” prefix to the address, but only IPv4.

  1. Melissa Lookups

For starters, this server boasts a lovely user interface, easy-to-use features, and offers support for both current versions of IP addressing.

Its lookup tools are similarly user-friendly, offer all the relevant data for IP tracing, provides Google Maps and Street View features, and even allow users to download lookup data in XML and JSON formats for markup and programming purposes.

All that said, however, there is one thing about this otherwise perfectly good website that might be less than preferable: pricing. Not only does the option for premium registration exist, but it is also mandatory for multiple IP queries and even using the JSON and XML download function.

Although this might not appeal to many, this website provides many mapping and technical services in affordable packages, including access to top-shelf IP lookup APIs and geolocation resources. So, if you can afford it, checking some of their plans might be worth your while.
