Class & Subnet - IP Scheme is fudged up

I have an IP range of, 192.168.0.1 - 192.168.3.254 with a subnet of 255.255.252.0

The address range is class C and the subnet is class B.

Will this ever cause a problem?

How important is it to stay within the class ranges, everything on the network is working correctly?

Is it worth changing the address to a class B range, 191.116.0.1 to 192.116.3.254?

Fist of all your subnet is fine. Secondly, once you subnet a network it is not considered "class" anymore, it is "classless." just make sure auto-summarization is turned off on your router. Also RIP and IGRP will no longer work.

Also RIP and IGRP will no longer work.

May I add my two cents?

To be exact, RIP v1 won't work anymore... RIP v2 is classless and will handle this subnet without any problem.

good call!! RIPv2 is hott stuff

EIGRP is more exllent if u have only cisco brand routers all across
network

OSPF ANYONE? lol thats my favorite there.
