Get Whois Info On All Your Accounts
Posted: Wed Oct 05, 2005 9:18 am
I have to find out what name servers my clients are pointing their domain names to. Specifically, I'm searching for names that point to a reseller's name servers so I can notify them that the name servers are changing. If you're ever in the same boat, this program will help find positive matches for domains that are pointing to the name servers in question.
I'll pre-empt this with the bad news. Unlike the one on Ala's servers, this script expects a functional whois that can handle a wide variety of TLDs. I recommend you install:
jwhois version 3.2.2+, Copyright (C) 1999-2003 Free Software Foundation, Inc. or you can run it on a server such as those at EV1 that have this as a standard program.
Moving on....
The results look something like this:
Hope this helps somebody as much as it has me.
