Keywords: subnets IN-ADDR.ARPA Message-ID: Date: 9 Apr 91 08:41:48 GMT Sender: news@ccu1.aukuni.ac.nz (News Owner) Organization: University of Auckland, New Zealand. Lines: 26 Nntp-Posting-Host: aucs7.cs.aukuni.ac.nz Our domain is cs.aukuni.ac.nz and the server(s) look after addresses 130.216.32.x through 130.216.39.x. These being subnets 32 - 39 of 130.216. The domain aukuni.ac.nz is looks after all other subnets of 130.216. My problem is obtaining the hostname from the address using the IN-ADDR.ARPA domain. How do we tell aukuni.ac.nz's BIND server and our BIND server that request for the hostname of say 130.216.34.2 should be directed to the cs.aukuni.ac.nz. server while requests for 130.216.1.2 should be handled by the aukuni.ac.nz server. Currently aukuni.ac.nz's server attemps to handle such requests and of course fails. 2. What is the line "sortlist 10.0.0.0" in the named.boot file for? I couldn't see any doc which would tell me. (It was in an example named.boot file). rob@cs.aukuni.ac.nz Rob Burrowes -- Rob Burrowes rob@cs.aukuni.ac.nz.
