10.0.0.x or 192.168.0.x non-routable network - which should I use?

I am setting up a 2003 server network at school.  Is there some reason why I should be using the 192.168... range instead of the 10.0.0.x range?  When the DHCP server suddenly stops functioning, then the 192.168.x.x range is automatically adopted by each PC. Understood.  Is this the reason why I see so little reference to and use of the 10.0.0.x range?

No reason you should use one over the other except for the range of the scope. If you get the 192 Address on a PC have you tried seeing where it is getting the address (possibly a Router / Firewall)? If you run:

ipconfig /all

At the command prompt it will tell you whether or not it is using DHCP, and the Server Address if it is.

Just for reference:

10.0.0.0/8 is a Class A Scope, with all addresses between 10.0.0.0 and 10.255.255.255 usable (scope includes Network and Broadcast Address).

172.16.0.0/12 is a Class B Scope, with all addresses between 172.16.0.0 and 172.31.255.255 usable (again including the Network and Broadcast Addresses).

192.168.0.0/16 is a Class C Scope, with all addresses between 192.168.0.0 and 192.168.255.255 usable (one last time for those Network and Broadcast Addresses).

I keep forgetting to add things...

If no DHCP Server is present (and the Network Connection is active) then an Address from the Automatic Range is assigned:

This is a Class C Subnet (/16) with Addresses in the Range 169.254.0.0 to 169.254.255.255.

Is the automatically assigned 169.254 range also non routable?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Although non-routable is a bad description, all IP ranges are routable, just some aren't used in the public IP space ;)
