[cobalt-developers] Proper DNS setup

["Kevin D" <kdlists@xxxxxxxxx>]

I have never run a DNS server, so I am somewhat unfamiliar with setting up
address/mx/ptr records. I have read about it a bit, but a few things confuse
me on the RAQ:

First, whenever I generate an address record, I have read that I should
generate a reverse-lookup (PTR) record. If I have multiple domains on a
single IP, should I still be generating PTR records? (ie have one IP
pointing at multiple domains?)

Second, I have been assigned 29 as a subnet, but the automatic reverse
generation is always IP / 24. I assume I should probably change this to IP /
29? I also noticed the warning about non 8 bit subnets - should this concern
me?

I also read that telnet is a good harbinger of reverse-DNS problems. When I
set the RAQ to use itself as primary DNS, I definately do experience telnet
problems (ie it takes an extremely long time to connect).

Thanks,
Kevin
