7 Slightly Unexpected Use Cases of Bulk WHOIS

The Internet has created plenty of opportunities to launch websites and run ventures, yet achieving transparency and accountability online is more complicated than ever in today’s digital landscape. Pretty much anyone anywhere in the world can buy any domain name — leading to situations where identities get blurred and giving scammers plenty of opportunities to plan and execute multiple types of cyber attacks.

Fortunately, publicly available information such as WHOIS records includes details of domain owners and registration activities to help businesses and entrepreneurs find out who is actually on the other end of the web.

Discover Which IP Range a Suspicious IP Belongs to by Using IP Netblocks WHOIS Data Feed – and Keep Your Network Safe

In order to keep your site and network secure from malicious attacks, spam, fraud and hackers, it’s important to identify and then promptly block any suspicious IPs before they can make any real and lasting damage on your network. Cyber attackers, however, are very skilled at masking their IPs (not to mention that they are extremely persistent and do not give up easily) and finding out where they come from can be difficult – but far from impossible.

That is why we created this handy tool which will help you discover which IP range a particular IP belongs to.

If you're building a website (or API) using Flask, it's often useful to know where your visitors are coming from: the US, the EU, someplace else? The process of locating a web user is typically referred to IP geolocation, and unfortunately, it isn't simple.

The reason it isn't easy to get IP geolocation data is that there is no standard mapping of IPs -> location data. Most companies get this data by purchasing it from GeoIP aggregators that piece together lots of different bits of information to build an accurate database of IP geolocation data.
