Hi everybody; If I knew of a good named newsgroup or mailing list, I'd be on it. However, I though the FreeBSD guru group would be well equipped to answer my question :-) I am attempting to set up a master zone file for a small block of IP addresses that I have received from my upstream provider. Basically, I own x.y.z.96 through x.y.z.103 (8 IP addresses). The rest of z. is not mine to control. Currently, my ISP has created zone files for www, ftp, and MX/mail. However, they will allow me to run my own nameserver, and will handle the reverse DNS entries on their end for no cost. I intend to begin virtual hosting (name based, on two of my IP addresses). So, the hosts, then: x.y.z.96 - www 97 - mail 98 - ftp 99 - *virtuals 100 - ntstn 101 - tucows 102 - ns1 103 - ns2 So, for any additional domain names (on .99), I need to create entries in my master zone file. I have the following in my named.conf: zone "96/8.z.y.x.IN-ADDR.ARPA." { type master; file "hosts.rev.z"; }; no secondaries defined, and I have temporarily disabled forwarders to aid in testing new setup. I DO have the default "." root entry intact. Question: What is the proper way to mask the IP addresses so only IPs 96 thru 103 are controlled? I've looked at RFC2317, and the above is the best I could come up with. So, hosts.rev.z resembles the following: $ORIGIN 96/8.z.y.x.in-addr.arpa. @ IN SOA ns1.sasknow.com. root.sasknow.com. ( 19990821 ; Serial 3600 ; Refresh 900 ; Retry 3600000 ; Expire 3600) ; Minimum 102 NS ns1.sasknow.com. 103 NS ns2.sasknow.com. 97 PTR www.sasknow.com. . . . etc Again, is my masking correct, or have I messed something up there? Have I specified the hosts correctly? All of these addresses (currently) reside on the same box. In /etc/resolv.conf, I've removed all DNS entries except for x.y.z.102 and x.y.z.103 (equivalent to localhost). I want to be sure that I have this set up correctly before I go ahead and make a mess. I'm also assuming that I have to ask my upstream provider to delegate those IPs to my control before anything will take effect. Is there a way for me to test my configuration WITHOUT upsetting connectivity with my hosts that are already maintained by my ISP? I really don't want any downtime due to my own stupidity :-) Thanks, Ryan Thompson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
