What does aarnet.edu.au has to do to propagate ? If you can answer this last question correctly then we can proceed with the discussion. How does a query propagate? Well, to paraphrase Section 2.6.2 of that book that's right in front of you(*): - The local nameserver gets a request for www.example.aarnet.edu.au. It doesn't know where this is, but it does know where all the root nameservers are. So it picks one of those and asks it. - The root nameserver says, no, I have no idea where www.example.aarnet.edu.au is. But I do have this list of nameservers that are authoritative for the .au domain, maybe one of them can help you. The local nameserver picks one, and sends the query for www.example.aarnet.edu.au to it. - The .au nameserver says, no, I have no idea where www.example.aarnet.edu.au is. But I do have this list of nameservers that are authoritative for the edu.au domain, maybe one of them can help you. The local nameserver picks one, and sends the query for www.example.aarnet.edu.au to it. - The edu.au nameserver says, no, I have no idea where www.example.aarnet.edu.au is. But I do have this list of nameservers that are authoritative for the aarnet.edu.au domain, maybe one of them can help you. The local nameserver picks one, and sends the query for www.example.aarnet.edu.au to it. Do you see where this is going? The query keeps propagating down different levels until it finally hits a server who says Ooo! I *know* this one! and replies. It sounds like a lot of traffic, but the local nameserver also caches all of those replies it got along the way to resolving that query. So if the next query it gets is for, say, www.monash.edu.au, the local nameserver will say I don't know where that is, but I've already got this list of .edu.au nameservers that is still fresh in my cache, I'll ask one of those. In a perfect world, the root servers wouldn't get that much traffic at all, really, thanks to caching. But there's a *lot* of poorly configured nameservers out there. http://www.bind9.net/dnshealth/ makes the claim that 98% of queries to the root servers are unnecessary, and is full of lots of other interesting DNS-related factoids. Anyway, the point of all of this is, *all* of the propagation in DNS happens downwards. The root nameservers seriously don't know the first thing about subdomains of aarnet.edu.au, and you can verify this by sending a non-recursive query to one (using the +norecurse option to dig, for example). Not only do they not know whether a particular subdomain exists, they really don't care whether the object it resolves to (not all DNS records are IP addresses...) belongs to the domain owner, or Dexter Plameras, or whether it even exists on the public Internet at all. I desperately hope this clears up any misunderstandings. * I have the fourth edition. May be slightly different for others.

The technical aspect of the job is the easiest. If everybody can be authoritative by doing what J Waugh had done there will be chaos on the internet. The whole point: perkypants.org is not authoritative for plammered.perkypants.org. I know how he does this. But fortunately, perkypants.org cannot make a commercial proposition out of these activities. If perkypants.org makes money by using someone else public ip address without authority this is stealing.

Technically aarnet.edu.au doesn't need to propagate anything up to the ROOT servers. That is not the way DNS works, rather the client contacts the ROOT servers and then goes down from there (ignoring any caching). So really, aarnet.edu.au doesn't need to propagate anything at all. Do you mean once aarnet.edu.au enters www.example.aarnet.edu.au IN A 203.7.132.1 it will be propagated ? This is wrong. aarnet.edu.au is only a branch in the DNS trees. What does aarnet.edu.au has to do to propagate ? If you can answer this last question correctly then we can proceed with the discussion. How does a query propagate? Well, to paraphrase Section 2.6.2 of that book that's right in front of you(*): The KEYWORD here is authority as I explained in one previous post.

You only know the technical aspect of it. The technical aspect of the job is the easiest. Please tell me the bureaucratic process. A link to some site explaining it. People set up nameservers and names all the time, it must be published somewhere. Please enlighten us! If everybody can be authoritative by doing what J Waugh had done there will be chaos on the internet. CHAOS ON THE INTERNET! SNAKES ON A PLANE ! But seriously, the internet is like this, and it seems to work reasonably well. The whole point: perkypants.org is not authoritative for plammered.perkypants.org. I know how he does this. Yes it is that is the whole point. The nameserver that is associated with perkypants.org is authoritative for plammered.perkypants.org Wikipedia (http://en.wikipedia.org/wiki/Domain_name_system) explains this quite well. Ok, lets just turn this all around, if Jeff's nameserver is *not* authoritative for plammered.perkypants.org please tell me which server is. But fortunately, perkypants.org cannot make a commercial proposition out of these activities. If perkypants.org makes money by using someone else public ip address without authority this is stealing. I'm not sure where money came into this. How / why would Jeff be making a commercial proposition out of these activities? Again, just because you can, you do. Just as because you can hack someones Server you do. I don't. You might. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
