Hi Guys,
I was wondering, how do those sites do it? How do they provide these lists? Is there a way to create a script that would queue the domain registry?

Thanks.

i think they get access to each registry database and query the database.

although its not the zonefile access since it has specific listing of domains in RGP and pending delete, since zonefile access has only active/nonactive domains including on-hold or no-nameservers domains too

Sorry I did not understand all that well. Do they spider the whois servers?

yeh i want to know as well.. ive used 2 domain scripts like this and am very intreged as of how they do it :)

no the registries (http://www.iana.org/gtld/gtld.htm) provide access to their database and they search into it

search for zone file access via google, although i know zonefiles doesn't mention which domain is in RGP or pending delete or on-hold, it just show active domains and if u compare it with tomorrow's domains u will get the new added and removed (onhold for example) domains

With the zone files, I can only find who is the host, nothing more..

yeah but you can compare today's zonefile with yesterday's zonefile and if there is a domain which exists in yesterday's zonefile and not in today's i think they do a whois for that domain to find if it went ON-HOLD or redepmtion period or pending delete or available.

not sure if there is any other way or some sort of database access at verisign that gives on-hold, RGP or pending delete status

I bet those scripts eat up the CPU like nothing..
