The best thing to do is to use a DHCP server and DNS server that are
"connected" somehow. Then hostnames "just work". Or you can
statically assign IP addresses in the DHCP server so that DHCP clients
always get hard-wired IP addresses that match up with the /etc/hosts
file on the DNS server.
I use OpenWRT for WAP, DNS, and DHCP, and it all pretty much "just
works". When a DHCP client is assigned an IP address, the DNS server
knows about it and you can access it by it's hostname just the way you
would with a static setup.
For various reasons, I assign static IP addresses to a number of
devices, but I do it via the DHCP server's configuration, not by
configuring each individual device.

I would think first is to reach consciousness on what the
reserved/system IDs are supposed to be once that has been done we can
start looking at what is the best approach to implement and or fix
things that might break because of it.
We admins that are in mixed *nix environment and are stuck with legacy
uid/gid already have to *fix* the idiocy being done in configs and
application where the min UID/GID is set to anything but 100 (
restricted range ).
Basically we whom are living in and running legacy/mixed OS environments
are fucked already the main thing here is to reach consciousness across
distro's and preferably *nix platforms so we dont be in this crappy
situation again after 10 - 20 or 30 years time..
