My domain soft is ready but need more .COM whois servers

[xtmoney]

dear NP users
my software is ready but i need more working whois .com servers like:
.com;whois.internic.net;No match;
.com;whois.crsnic.net;No match;
.com;whois.tucows.com;Can't get information;

i made research and i found a lot whois servers but all of them give me false information..example - the domain exist but whois server return false info and say that domain IS NOT EXIST.

for now i need only tld. COM .maybe 10 servers are ok.
i need them to work on port:43 for my soft..

Note..
anyone who supply me with 10 working WHOIS .COM servers will get reward:20$

For most TLDs the WHOIS is thin, meaning you have to get the information from the registrar which is holding the domain name. If a domain is registered at Godaddy, only whois.godaddy.com has the info. If a domain is registered at Moniker, only whois.moniker.com has the info. And so on...

Only a few like Godaddy and NetSol actually forward your request to the appropriate registrar if they aren't the registrar, the rest just return that the domain doesn't exist if they don't hold the domain. For example, if a domain is registered at Godaddy and you try to look it up at whois.onlinenic.com, they'll tell you the domain doesn't exist because it isn't with them.

You're missing the most important (first) step. What does your software do? If you're just trying to check availability, there is a much easier and faster way to do it that works for every TLD.

thanks for help.
i want more .com whois servers because of speed. When i have more working proxies.with more working whois servers then i can check fast all 4llll com for example.
i make my soft to check availability only .but to work fast not slow like other softwares.

The trick for checking availability is to not even look at the WHOIS, most registrars are pretty slow when it comes to getting a response on whois.someregistrar.com. Run that through a proxy and you're looking at 3-4 seconds per availability check... times 456,976 LLLL.com and it takes like 3 weeks to run the scan.

What you do is hit ext.whois-servers.net on port 43 and send it the domain name, just like you do for the WHOIS check. So for a .com lookup you hit com.whois-servers.net, for a .net lookup you hit net.whois-servers.net, and so on. It will give you back the thin WHOIS (registrar, creation date, name servers, whois server, etc) if the domain exists, or will say 'no match for domain.com' or 'not found\n' otherwise. This is all you need to know if it is available.

So all you do is hit the correct server (ext.whois-servers.net), check the results for 'no match for' or "not found\n" and if either is present, the domain is available, otherwise the domain is taken.

You can usually get about 15 checks per second depending on how fast your server is. That knocks your three week scan down to about 8.5 hours. Still not great, but what can you expect for it not being a multi-threaded desktop app

I wrote a more detailed post about it here almost a year ago:

And here is an example script for bulk-checking availability:

Hope that helps.

this is great post..appreciated much
you mention that can check up 25k domains for minute with software? is this true?
what type server you need for bulk_availability.php your script?
is there any specific to know before run it?
