New API: IP whois API – IP lookup

After the announcement of our Whois api with XML output (back in June) and our Domain Score API (back in May), we are now introducing our 15th API. It’s a bit hard to pronounce IP whois API, but the benefits will certainly outweigh that issue. There are many IP checks services, and some we already have. For example our IP geolocation API so you might be wondering, what is the difference between our IP geolocation API, and the new IP whois API?

Just by looking at the output it is clear that geolocation API is focused only on the geolocation (country, city), while the IP whois API is a more robust API with complete information around an IP address. You still get the country code of the IP address, but you also get IP owner information like organization owner name, address, phone, abuse email, date of IP address creation, and other information (check screenshot below).

We would love to hear your feedback on this API, and as with all new signups and all our APIs you are allowed to make 500 requests for free.

Benefits of IP whois API

If you track the IP address of your website visitors or application users you can programmatically:

  1. check the country of their origin
  2. get abuse email address in case this IP is a part of DDOS attack or other malicious activity
  3. detect hosting providers for certain domain names
  4. How are you using IP lookups? Let us know in the comments
