[SNMP4J] Plea for help from an SNMP beginner

[Mark Brand]

Thanks for your help - i thought I finally had the addressing methods
right...
It seems to work now, after changing the address.

One more question though - some of my previous code didn't work until I put
the ".0" at the end - is it always superfluous,
or is there some circumstance under which I should use it?

Thanks again,
Mark
