Monitoring Hosts that use DHCP

Nagios Nagios Configuration support

I have several hosts that I’d like to monitor, but their ip addresses are constantly changing. Is nagios capable of allowing a user to define the host without the ip, but just the hostname?

Thanks,

Just realized that field doesn’t require numbers. I was able to input FQDN into the “address” field of define host {}

Thanks,
