If "my network" is a TCP/IP LAN, you need a name server somewhere on
it (your ISP will _not_ provide anything of this nature for your
LAN, if you only have a UUCP gateway), or else you need to put all
the host names in the /etc/hosts file of each host (or whatever the
equivalent to /etc/hosts is for whatever other operating systems the
hosts on your LAN employ).
If you don't run a name server, several programs, including sendmail
and emacs, need to be configured so that they do not try to do DNS
lookups.
If you set up a name server, the only complication is that it will
also be the root name server "." within the universe of your LAN.
The book "DNS and BIND" published by O'Reilly shows how to configure
a local-root name server.
If you set up a nameserver you have a standard, unproblematic
environment. You can do without, and things should work, but you
may have a few unexpected problems to solve.
I'm not sure why you *really* want to avoid the obvious. I guess
you need to decide between a solved problem with a standard
solution, but one which you don't want to have to understand, and
some unknown but hopefully small number of other problems which may
not have standard solutions but which hopefully you may be able to
solve.
