I agree! I'm at a client right now that has subnetted their VLAN with /21
addressing (2046 addresses per) and then added up to 4 secondary addresses on
top of that. Granted they are not using all the available addresses in the
space. Big and flat is generally not good. Especially in chatty
environments
(Appletalk, Novell IPX/SPX, etc.). If you recall a discussion a short time
ago, ball park numbers of nodes on a VLAN are:
Per Cisco's recommendation:
1) 500 node for 1 IP segment
2) 300 node for 1 IPX segmnet
3) Mixed enviroment 200
4) Netbios 200
5) Appletalk 200
