Subnetting question

chibi2666 · 02-18-2009, 09:59 PM

HI,

a subnet mask of 255.255.255.192 and the first network address of 64.5.96.0, I'm trying to find all of the network/broadcast pairs?

I got 64.5.96.0 255.255.255.192

64.5.96.1 255.255.255.224

Can you please help me with this problem.

Thanks

If I don't have time to calculate networks on paper, I use this: http://www.subnet-calculator.com/

Quick and easy.

@routers: even better - a utility already available on your server.
