If you should search for an IP address it would be nice if a widget appeared with the WhoIs information for that IP Address.
Let's take the IP Address for sun.com for example, 156.151.59.35.
https://kagi.com/search?q=156.151.59.35
From the WhoIs data we can get an address, 500 Oracle Parkway, and owning company, Oracle, as well as contact phone numbers and abuse email address.
In theory, this should be easy for you to present and cheap to obtain on-demand with no caching required.
You can see what dedicated sites do with the same information: https://ipinfo.io/156.151.59.35
