Well, as Peter has said (to me, at least), netreg is not a security
system. It depends on client machines cooperating by using DHCP.
I don't know much about snmp, but I would imagine it also requires a
degree of cooperation from the clients (Install some sort of agent on
the client? I invite someone more knowledgeable comment on this).
The only thing you can do to enforce compliance is to block all
non-registered IP addresses with your network router(s). You'd have
to get netreg to programmatically communicate with the router(s) to
enable addresses as they get registered. (I've been wanting to look
into possible netreg-CISCO router communication, but I ran out of
those "round-to-it" thingies :-/ ).
That's as far as my thinking takes me.
