If you want a predictable LAN, then I really only see two ways to
manage that without major pain:
1. Run a DHCP server with a DNS server...
2. Manually configure each device to have a fixed IP.
I think you left out a third method, which uses part of your version 1.
3. Use a router and set static addresses for each device. Today, all
routers act as DHCP servers, and setting a static address/MAC address
pair in the router setup ensures that any listed device will get the
same address every time. The router does not have to act as a DNS server
for internal devices: it passes external name calls to the gateway.
You only need to access the router setup when there is a new physical
device being added, such as a new phone. You can give it the same old IP
but that will now be paired to the new MAC. And then the /etc/hosts file
is merely a memorandum file to keep track of things.
