What's your IP Mapping Layout?

I'd be interested to see how other Admins layout their IP Addresses. Do you stay simple at 192.168.1.x or do you keep wireless clients on 10.0.0.x etc.

Just wondering really. I prefer to stay at 10.x.x.x since there is more room to play with but have seen others differentiate in different (or sometimes random) ways.

192.168.1.x is for home networks and SMEs. You won't find it in proper enterprise environments, especially when you start dealing with dozens of sites and all the routing involved.

Our enterprise network (MPLS) is on a 10.X. X. X subnet.

The project I work on support for is also an MPLS network using the 172.16.X. X. (CIDR) Subnet.
Each site has a different value for the 3rd octet.

It all depends on how big network you plan.
For big network that requires a huge pool of 16 million private IP addresses, multiple sites/subnets you would use Class A network 10.0.0.0 - 10.255.255.255 (10/8 prefix).
For medium-sized network that requires 65000 private IP addresses you would use Class B network, 172.16.0.0 - 172.31.255.255
Commonly used IP range on smaller network for easier addressing of 254 IP addresses you would use Class C network, 192.168.0.0 - 192.168.255.255. May not necessarily be smaller network but network managed in smaller blocks. Not very flexible if you want to create VLANs/subnets. Best for home or small office.

I personally have a mix of all three, as I've inherited it from previous admin. It is a pain in the arse to manage and I slowly migrate it to Class B.
