If some software wants to know the IP address of TLM before the
network is up, there's no point in handing it 192.168.M.N,
so you use a loopback address to itself.
However, putting TLM on the first line can apparently make
localhost.localdomain into the canonical name of the system,
which is probably not what you want.
BTW I don't know where your .com came from in the first line.
