Best software to bulk check if domain is available to reg?

[kiltbelt]

Hi

Can anyone recommend any software that can bulk check a domain name list say 60k in total domain records and check to see if they are available to register?

Thanks in advance

The problem with bulk checking so many domains is that you are going to run into trouble with the number of lookups at both the registrar and registry. Personally, I know of no software which can do that.

I'm not aware of any software that does it but you can program a small script that interfaces with the Dynadot API and makes free calls to its domain availability API.

tons of free php bulk checking scripts available.. no need to do it thru registrar interface/API if you have a little php knowledge (bash, perl, python ..anything goes)

simple example is in this thread: http://www.namepros.com/code/280961-php-bulk-domain-availability-check.html

to avoid IP ban tweak sleep() and switch DN servers (2-3 is enough, i use com.whois-servers.net for .coms, search for a couple alternatives) for every 1,000 or so names.. you should be able to check 60K .com only names in 10-12 hours or faster from one IP with no problems on registry side
