I guess I am a Novell guy, so here's what I think you mean. The only time I
have seen a problem with the IPX internal network number is in NT. If you
have multiple NT servers on the same segment, you MUST change the internal
IPX number on the box -- because Microsoft defaults it to 0x1 and they must
all be different. Novell generates a random number (as others have said)
when the server is installed, but you can override that creating the
possibility for duplicates.
If there ever is a duplicate, you will know VERY quickly, since NetWare
advertises this ever minute. Same as if you tried to add a duplicate
license on another server, but that only advertises every 2 minutes. It
doesn't take long for the CEO or CIO to give you a call to find out what
that message means...
On Cisco routers, you need the Internal IPX number pretty much only for
NLSP. HTH,
David

That's interesting. I'm not a Novell guy but I recall having to change this
number on a few occasions in order to make a box 'work'.
If I have two NetWare servers, each with a single NIC, attached to the same
segment, would the internal network number need to be set to the same value
on each box? Someone please educate me on this.
Hmm.. Will a NetWare server advertise a route to the internal network via
connected interfaces configured for ipx rip? Will the type 4 and 7 SAP's
appear as if they are on the internal network or the nearest outbound
connected interface of the NetWare server?
Would I ever need to filter on this number?
Thanks,
-Derek

I don't believe the Internal IPX network number is .0001.0001.0001. I think
it is x.0000.0000.0001 where x is the Internal IPX network number and 1 is
the associated MAC for it. You cannot/should not have two servers using the
same internal IPX network number. If you do the servers will not function
properly.
