Hi Kp, Before we take this offline. Let me add one more thing. The reason I'm not using whois, is because I have more than one query to make, and I have heard that they frown upon automated access. But if you can offer anything else, I'll be more than happy to contact you offline. Take care, Sina -----Original Message----- From: speakup-bounces@xxxxxxxxxxxxxx [mailto:speakup-bounces at braille.uwo.ca] On Behalf Of Kelly Prescott Sent: Tuesday, May 24, 2005 3:48 AM To: Speakup is a screen review system for Linux. Subject: Re: Dns question ok, here goes a brief informational post about DNS... there is ***no*** complete source of information about domains registered etc... There is, however, many registries that maintain information about various domains... With that said, there is a way to do a better job of finding the availability of a domain. checkout bwwhois available from http://whois.bw.org This client, among other things, has a table of which registrys administer which top-level domains... Hope this helps. email me privately if you need more info. kp On Mon, 23 May 2005, Sina Bahram wrote: > Hi all, > > I hope everyone is doing well. > > I appologise for the off topic message, but I know that a great deal > of you are enthusiasts in networking, and are quite more well versed > than myself in DNS, which is where my question arises. > > I am building a utility that checks to see if a particular domain is > registered or not. > > Think of it like a stripped down personalize version of whois, if you will. > > My problem is that I have yet to figure out the absolute minimum > requirement, in terms of something that can be programmatically > determined, that says: hey this .com is taken. > > I am using the net::dns module from CPAN in my perl script, and I have > tried looking at the SOA record, because that is what I have picked up > from my documentation and google runs as being the absolute requirement. > > Yet, I still get websites like > > www.hospital.com > > And > > www.patient.com > > Which do not return SOA records to my program, yet they are owned ... > I think both of those, since 1997. > > So, my question is, what is the absolute minimum?
