Domain Whois Information Algorithm

Is it possible to run an algorithm of all the verisign (and maybe individual registrars 开发者_运维知识库whois) domain data to call out qualified information?

There is a Zone File Access program that is operated by all the registries, as a condition of operating the TLD by ICANN, that will allow you to get a list of all the domain names that are registered. There are strict rules on what you can do with such data but it might be a route forward.

I believe that there are existing companies that have done this and you can query them instead. It all depends on how much data you require as to which method is cheaper.

Hope that this helps
