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
