1 Running an authoritative name server on a small home lan as training
2 exercise. And using DNS and Bind 4th ed as a guide.

4 A quick sketch of this network(There are more hosts on it
5 but for simplicity):

7 (All have prefix 192.168 and netmask 255.255.255.0)

9 INTERNET

12 NETGEAR (consumer grade router)
13 reader | 0.20 fwobsd

15 | 0.4 | 0.3 | 0.5 | 0.19

22 So I have two networks here.. 192.168.0/24 and 192.168.1/24
23 M1 and M4 both have 2 nics and addresses in 192.168.0 and 192.168.1
24 as shown... (if mail doesn't mangle my asci production too bad.)
25
26 My problem is how to integrate 192.168.1/24 into my zone.files
27
28 The reverse-pointer zone.file for 192.168.1 is where the rub is.
29 I'm very inexperienced with routing in general and nameservers in
30 particular .... setting up a home lan nameserver is a training
31 exercise for me.
32
33 Where I get confused is what is the origin `@' for this zone?
34 Can I use `@' or need to spell out 192.168.1?
35 What happens to my domain... `local.lan' does it still cover what are
36 now really two numeric domains 192.168.0 and 192.168.1?
37
38 I've tried various combinations in the reverse zone for 192.168.1, but
39 all I've tried have has one or another problem loading, or being
40 ignored.
41
42 The reverse file for 192.168.1 is below and at the end .. after names
43 logs is the db.local.lan zone file.
44
45 (naming convention stolen from DNS and Bind (4th ed))
46
47 I'll post, at the end the named log output from this zone.file as
48 an example but as mentioned, I've tried quite a few combinations
49 unsuccessfully. I can post them all but hopefully someone will see
50 the problem I've created. This one causes the 2 address in 192.168.1
51 to simply be ignored... other versions have different reasons for not
52 loading properly.
