It is a network protocol, so should be over some network.
It could be loopback interface, I suppose it could be over a
different network than what is being managed ('out-of-band').

I don't know in this specific case, in theory it could be either.
All that is required is that the DNS server/router respond to
SNMP commands.
There are a various helper programs for MRTG available.

If there is an OID for it in the MIBs, it is open for 'management'.
For basic SNMP, it reports in response to commands, unless a trap
is triggered.
BSD has OIDs for kernel configuration, but I'm unsure if
these are used by SNMP, but if so, then their sysctl
command for changing kernel configuration on the fly
is an extreme example.

SL answered this. there may be an auxiliary script that can be
adapted to help on this.

If you want to plot stuff, MRTG could hardly be a mistake.
I don't have a home network yet, so I can't speak on particular
experience, but MRTG has been ported to OS/2, and unless
this version is drasticly different from others, it
requires Simon Leinen's Perl SNMP package, which will
also provide configuring capabilities.
The O'Reilly 'gopher' book (Perl for System Administrators)
recommends using the UCD package for scripting, which are
some stand alone programs.
I'm curious how easy they are to compile under EMX etc.,
(probably very) and these should work with Rexx also.
