There are a number of WhoIs scripts knocking around, this is my version. Something of a long development cycle since I started this last year, got busy, then finished it today.

Get-WhoIs has been incorporated into a script module: Indented.NetworkTools.

It has a couple of dependencies, it needs both NetShell (for sockets) and DnsShell (to attempt to locate a WhoIs server). I use whois-servers.net to find a server for name lookups, and I use ARIN as a starting point for IP lookups (with a recursive call to get detail).

My test set is small, if you happen to try it and find something doesn’t work please let me know.
