IP Subnetting

IP Subnetting

IP Subnetting

I have a simple network. Class C, I am running out of IP address and need to change to a class B to provide more host nodes. Here is my question as one who is not a network guru, Can I just change the subnet mask to /16 without changing the 192.168. to 172.16.?

RE: IP Subnetting

The range of through is reserved for private use. See: http://en.wikipedia.org/wiki/Private_network Yes, you can change to 192.168 /16 without conflict. You will need to adjust all machines on the network so that they have the correct mask or you will wind up with routing issues.

RE: IP Subnetting


Instead of creating one big flat /16 network you should just create another vlan with a /24 and route between vlans (very simple to do). As your network grows it will be a lot more stable than one big /16 network.

RE: IP Subnetting

With a larger segment you will have a lot of broadcast traffic.
With VLANs or /24 that is cut down
