Hi,

I want to display domain age on my website. The obvious answer is to find the creation year on whois. This is fine except I need to query 130.000 domains a day and most whois servers have 2000 query limits.

Moreover web based whois query works slower. Command line based query is faster but there is a redirection from whois.internic.net to a random whois server. I think the internic whois has no limit but my programmer doesn't know how to avoid the redirection and to query internic with command line whois.

What are your suggestions on this issue? I know about php whois library. We tried that.

You need to get a list of servers and query them round-robin. Just remember, anything more than one query per two seconds (especially at your volume) will trigger abuse.

Here's a couple to start you off..

whois.crsnic.net
whois.networksolutions.com

Btw, it would help tremendously to distribute this. Get a few 5$ VPS's

whois -h whois.internet.net example.net | grep -i creation
????: NamePros.com http://www.namepros.com/programming/691037-how-to-find-domain-age.html

also the terms for whois.internic.net explicitly state no high volume automated lookups.

You're just going to hve to get a bunch of different VPS or something and lower the lookup rate to be below the threshold.
