Please Help!
Our primary DNS server is a sparc-station 9 and our secondary is a Tru64
machine, both running BIND 8.3.4. Our domain is 146.229.0.0 We have just
received request to support a vlan with private addresses(10.0.*.*) within
our domain. We are having difficulty making this work, especially reverse
mapping for the private addresses.
Here is what we have tried:
Added the following to our named.conf:
zone "guest.uah.edu" {
type master;
file "guest.hosts";
};
zone "0.10.in-addr.arpa" {
type master;
file "guest.rev";
};
; Host file for guest.uah.edu
@ IN SOA uahis1.uah.edu. root.uahis1.uah.edu. (
04082309 ; Serial
3600 ; Refresh
1200 ; Retry
1209600 ; Expire
14400 ) ; Minimum
IN NS uahis1.uah.edu.
IN NS email.uah.edu.
IN NS spunky.uah.edu.
guest IN A 10.0.204.16
gateway IN A 10.0.207.254
;
; REV file for guest.uah.edu
; Address to hostname mappings.
;
@ IN SOA uahis1.uah.edu. root.uahis1.uah.edu. (
04082309; Serial
3600 ; Refresh
1200 ; Retry
1209600 ; Expire
14400 ) ; Minimum
IN NS uahis1.uah.edu.
2.1 IN PTR uahis1.uah.edu.
16.204.0.10 IN PTR guest.uah.edu.
254.207.0.10 IN PTR gateway.uah.edu.

Here's what happens when we try to resolve entries from the primary(uahis1).
bash-2.05# nslookup
Default Server: email.uah.edu
Address: 146.229.1.200
> server uahis1
Default Server: uahis1.uah.edu
Address: 146.229.1.2
> guest
Server: uahis1.uah.edu
Address: 146.229.1.2
*** No address (A) records available for guest
bash-2.05# nslookup gateway.guest
Server: email.uah.edu
Address: 146.229.1.200
Non-authoritative answer:
Name: gateway.guest.uah.edu
Address: 10.0.207.254
> 10.0.207.254
Server: uahis1.uah.edu
Address: 146.229.1.2
*** uahis1.uah.edu can't find 10.0.207.254: Non-existent host/domain

Any help would be greatly appreciated!
Thanks in Advance.
