choosing a private ip addressing scheme for our Vlan's/departments.

because its private i dont really need to be conservative and use VLSM...
Should i use something logical? or can i use something that is easily remembered?

for example:

172.16.0.0   \16 for core infrastructure.
172.16.10.0 \24 for department 1
172.16.20.0 \24 for department 2
172.16.30.0 \24 for department 3 etc....

would that be ok?

or can you suggest the correct way to do this?

Many thanks!

Almost.

First, here are the notes on RFC 1918, which defines the IP Addresses to use for private subnets: http://www.faqs.org/rfcs/rfc1918.html

Take a look at what you are doing there. You have 172.16.0.0/16 for your core. But then you show 172.16.10.0/24 for department 1. Keep in mind that the 172.16.10.0/24 subnet is part of the already defined 172.16.0.0/16 subnet.

The only change I would make is to pick another 24 bit masked subnet to use for core infrastructure, unless you truly intended for all the department subnets to be subnets of a subnet.
