I'm trying to find the list of all whois servers for COM/NET.
Verisign is the authoritative registry for the .com, .net, .name, .cc and .tv domains.

**Possible solution:**
To find out the complete list of whois servers is to crawl through at least a million of them (via whois.crsnic.net) using the domain list from the .com zone file and read the official whois from the whois result. 

That way I could probably build a 90%+ complete list. I'm ready to go that route and post a result here but if anybody knows a better way/source, please do help. Thank you!
