I'm going to make a pitch for the IP-address based method.

Specifically, if you have a set of well known IP addresses for common
services, thus something like:

223.255.255.1 - Primary DNS
223.255.255.2 - Secondary DNS
223.255.255.3 - SMTP Mail
223.255.255.4 - Time Server

You could very easily support this in ANY network.  No additional
HW/software required.

Just IP addresses, which are completely free and as easily available as
tap water, right?

I run 3 of the aforementioned services on a box at home using a single
IP. Are you suggesting that I should need 3 IP addresses within a
specific range in a netblock to do so?

Somehow I fail to see how this is a particularly stellar idea.
