Apan Configurations

Actually I don't use IP-numbers at all in Nagios, only host-names. All hosts I monitor in Nagios then lives in my hosts-file.
It's safe to skip the adress-statement in the host-definition and leave IP-numbers to /etc/hosts. You also need to set up your name-service switch to always look in files first (I don't yse DNS on my Nagios-server).

The benefits with this is that you have one source where IP-numbers and host-names are stored. The problem begins when you have many hosts, then your hosts-file get quite big. But I still think its easier to manage IP/name matching via /etc/hosts then the adress-statement in Nagios.

I would prefer to monitor by hostname since we monitor hosts with
dynamic IP addresses.
