I’m in a similar spot as the OP, and one thing that is important to me about knowing the hostnames is that defining (then tracking) a hostname is the only universally-implemented method that lets me scan through the hosts on the network and understand what they all are. - I’m never going to remember MACs - Even when IPs are carefully thought out, if something happens to the DHCP server and it needs to be rebuilt, IP no longer tells you anything about what device it is Whereas hostname/DHCP client name shows up in almost every router UI, is viewable from any *nix machine on the network (when DHCP and DNS work together), and is typically a first-class citizen in the DHCP lease settings themselves. Super handy. As a side bonus: rogue hostnames are immediately obvious, but rogue MACs or IPs require investigation before you know whether they are benign.
