OK, but how do you differentiate the host with the service it provides? If
server A is hosting DNS, tomorrow it will get a different IP from the ISP
and anyone using that service on the IP from yesterday will no longer work
today. Your ISP should not care if you use DHCP or static, actually I've
never heard of an ISP using DHCP with more than a single IP. Tell them you
need static, they should understand since it's normal operation.
