How can I bulk download whois data from a database of URL's?

Hi!  I will start by saying yes, there is a way to get only the creation date from doing a Whois look up.  If it exists in the information returned by the query (which it does) you can easily grab it. If you are using the API, there is no restriction on the number of look ups you can do from a single IP.  You have to pay to be able to use the specific API you choose and it usually has a fee associated with the number of "look ups" you want to perform. I believe the https://www.arin.net/ is the governing body over the publicity of information associated with domain purchases.  There is also a European and Asian equavalent.  I find it rather confusing, but encourage you to read up on it yourself. As for the legality behind it, it is public information and unless someone pays for domain privacy you can grab it.  This is a grey area on the web. If you want to check out a bulk whois tool you can check out http://emailextractoronline.com Hope this helps!

You can get whois database daily updates from http://getwhoisdata.com/ Get many domains database in full detail. Every day almost 200K domains gets registered and many gets dropped. All detailed database is available. I see its the cheapest and best data so far.
