1197233 2011-04-26 05:50:00 Got a CCNA subnetting assignment here that I started today.

First I've got to do a classful subnet using the address 172.24.0.0 /16 for a few thousand hosts. I've been told not to use VLSM the first time round, which is fine.

But I've forgotten how to subnet properly.

Am I correct in assuming the first subnet would be 172.24.0.1 > 172.24.255.254, and the next would be 172.25.0.1 and so on?

Cheers guys :)

1197234 2011-04-26 06:47:00 Assuming you're assigning multiple /16 blocks, yes.

If you're wanting to divide a single /16 into multiple smaller blocks, then no.

1197235 2011-04-26 06:51:00 Well I've got to subnet a network using Rip V1 so can't use VLSM first, that comes as the second part because we were told the exercise isn't possible to complete 100% with a classful setup.

Fine enough, VLSM is something I understand. Just makes the numbers confusing sometimes if you don't organise the subnets in order of size first or whatever.

If so, could you please clarify it - as far as I can tell, there are no points I have yet to address.
