Can I have your input on drafting up some instructinos to pass to an webhost on what they must do to make me responsible for the reverse DNS of IP's assigned to me.
I have little experience of how reverse dns works in the internet world, I know what happens locally, but im unsure of what constraints I am under when people query there DNS and the root servers tell them where to go, I assume its for a large IP block or something, one DNS server for that block, in the root hints.
So how to get can I be responsible for reverse dns on a few ips in the internet world ?
often times it's just easier to get your server provider to modify the records for you, depending on setup granted as they have everything in one big fat file for each zone, and can just dump reverse information quickly. Personally we've got it half setup to tie into our customer information database (we get ip justification, it goes into the database, the hostname submitted on the justification is saved in the ip address table, then the reverse dns zones are generated from this table, so anything thats been properly jusitified and is in our database will automatically be setup for reverse with the click of a mouse ).
Some companies don't know how to do this. One of my friends has a class-C through cognet or qwest and their support staff gets lost when I ask them to give our nameserver authoratative access over the ip's.
