Hi all
I wish to brake the 192.168 network into 2 equal subnets what would be
ip ranges for these subnets and what would be there net mask?

Thanks

I think you want to RTF RFC1878.

You wan two "B/2" (17bit) nets?
192.168.0.0 255.255.128.0 192.168.0.0 -> 192.168.127.255
192.168.120.0 255.255.128.0 192/168.128.0 -> 192.168.255.255


But if yo uwan two "C/2" (25bit) as your Subject line asks
192.168.0.0 255.255.255.128 192.168.0.0 -> 192.168.0.127
192.168.0.128 255.255.255.128 192.168.0.128 -> 192.168.0.255

UUaarrgghh!!,

Sorry for shouting, but all strings "128" should read "254" here!

You cut bits from right to left.


Cheers, Jack.

.... and then find yourself a handy-dandy IP address calculator, e.g.

http://jodies.de/ipcalc

FWIW, I found this site via Google (http://www.google.com) web search
using the keywords

ip address subnet supernet calculator

Are you sure of that? When I write the ips and netmasks in binary,
it looks like substituting "254" for "128" in all cases would give
you one subnet with about 252 nodes and one with 2, which would
be unusable, since one's the whole network (254) and the other is
broadcast (255).

I'm sure some fine neighbor will enlighten us if I'm in error.

Thanks

So anyway, it was like, 00:39 CET Feb 16 2004, you know? Oh, and, yeah,
Rich Grise was all like, "Dude,

A 255.255.255.254 netmask gives you a pretty small subnet indeed.
