Basic DNS Config |
|
|
Simple question, on my Primary DNS server's IP config, should the primary DNS
server IP be the loacl servers IP address or the loopback address? Whenever
configuring this I've always used the servers IP address, but someone is
telling me I should be using the loopback address.
I suppose the loopback would work but I've never heard of that configuration
before.
Any thoughts? |

I am thinking speed wise they are about the same as neither will go out onto
the wire as the IP route layer will route it internally to correct listener
(loopback IP and normal IP both being normal TCP/IP socket listeners aside
from the fact that the loopback can not be accessed from external side of
NIC). You need to be sure your DNS is listening on loopback too if you use
loopback IP. I tend to like using explicit interface IPs, instead, as I
tend to think in those terms when doing diag and have some comfort in seeing
the same IPs the clients will be using in their dns resolvers and can ping
those IPs from local box or from another client on lan, etc. Your client
side resolver IPs will match that which your client's are using (normally),
so you "eat your own dog food" and not something different from your user
base.
