Want to know if there is any way to add custom RR type.(like ip ipv6)
Im trying to make a new addressing scheme, and want to use bind to provide name service. The addressing is not compatible with known ones, and thus need to extend to support mine. Is there any way to do this? preferably innately supported by bind9? ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

You should *really* document what it is that you are trying to do with this addressing scheme in an Internet-Draft and apply for a RR code point so that you won't conflict with anyone (65280-65534 are Reserved for Private Use, so you should be OK, but keep the above in mind...)...

Okay, this seems really nice place to start my work. But just for the sake of convenience, is there a way to rename TYPE# to something that I want? And how should I go about to implement conversion of data back and forth between octets and string rep. in the zone file, as A, , and most other RR types do? would that require me to go too deep on the src?

Re: Want to know if there is any way to add custom RR type.(like ip ipv6)
But just for the sake of convenience, is there a way to rename TYPE# to something that I want? If you dig (pun not necessarily intended) into the source of BIND you can actually change the source so that `named' can read your type from a zone master file and `dig' displays it however you wish. The way this is implemented in the BIND source is via a set of rather clever/complex macros. As Warren said though, you'll have to be very careful here, and it will only be useful to *your* implementation. Say you create a type called XXYY, if I query your server I'd see the TYPE representation and not XXYY. -JP ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Re: Want to know if there is any way to add custom RR type.(like ip ipv6)
Well, I'm going to run the modified bind on a local testbed disconnected of internet. So, no worries on others, this is just for test, and aid with actual protocol development. Thanks on the hint, now I have to find out where to dig first. Any knowledge?
