I've always liked DHCP reservations over static IP addresses for servers where possible for ease of management Single view of most servers from DHCP client list simple to change parameters globally ( default gateway, primary DNS, secondary DNS, etc ) without having to visit each server less likely to experience IP in use conflict from out of date tracking spreadsheets when adding new devices to the network etc, etc, etc but if your clients/applications use hostnames, then that's what I'd monitor for most checks, keeping a single/simple check using the IP address to cross verify against name resolution.
