Using subnet number zero? 1

[verland]

I'm setting up some point-to-point interfaces. Is there any problem with this ip address?

subnet 192.168.1.0
hosts 192.168.1.1 and 2
bcast 192.168.1.3
netmask 255.255.255.252

The calculator I'm using says not to use subnet zero, but I think it's a router issue. Any ideas?

i don't see any problem with it.

you rock. I wired it all up and it worked fine, like I thought it would....

that was a Cisco calc btw, hence the router doubt

Cisco IOS makes you declare ip subnet zero, so that's
understandable.
