Running an authoritative name server on a small home lan as training
exercise. And using DNS and Bind 4th ed as a guide.
A quick sketch of this network(There are more hosts on it
but for simplicity):
(All have prefix 192.168 and netmask 255.255.255.0)
INTERNET

NETGEAR (consumer grade router)

| 1.2 | 1.1

So I have two networks here.. 192.168.0/24 and 192.168.1/24
M1 and M4 both have 2 nics and addresses in 192.168.0 and 192.168.1
as shown... (if mail doesn't mangle my asci production too bad.)
My problem is how to integrate 192.168.1/24 into my zone.files
The reverse-pointer zone.file for 192.168.1 is where the rub is.
I'm very inexperienced with routing in general and nameservers in
particular .... setting up a home lan nameserver is a training
exercise for me.
Where I get confused is what is the origin `@' for this zone?
Can I use `@' or need to spell out 192.168.1?
What happens to my domain... `local.lan' does it still cover what are
now really two numeric domains 192.168.0 and 192.168.1?
Here's a reverse zone file for my home network. It's 10.10.0/24
but you'll figure out how to tailor this to your needs.
# cat pri/0.10.10.zone
;BIND DUMP V8
$ORIGIN 10.10.IN-ADDR.ARPA.
0 3600 IN SOA baikal.iproducts.test.
root.baikal.iproducts.test. (
20050421 3600 900 3600000 3600 ) ;Cl=5
3600 IN NS baikal.iproducts.test. ;Cl=5
$ORIGIN 0.10.10.IN-ADDR.ARPA.
2 3600 IN PTR volga.iproducts.test. ;Cl=5
1 3600 IN PTR baikal.iproducts.test. ;Cl=5
3 3600 IN PTR g40.iproducts.test. ;Cl=5
;10 3600 IN PTR wisla.iproducts.test. ;Cl=5
#cat named.conf
...
zone "0.10.10.in-addr.arpa" IN {
type master;
file "pri/0.10.10.zone";
allow-update {
10.10.0.1;
};
};
...
