Adding another Lan segment into a existing LAN

I have a Class C flat network How can add another segment as my IP address are running out

Hello,

you could either change the mask on your existing address space (from 24 to 23 in your case, which would give you an additional 254 addresses; that would also mean changing the mask on all your hosts). As an alternative, you could configure a secondary IP address on your LAN interface:

interface FastEthernet0/1

ip address 192.168.1.1 255.255.255.0

--> ip address 192.168.2.1 255.255.255.0 secondary

That would add another class C address space to your network. Your hosts in that new subnet would use the secondary address as their default gateway.

HTH,

You can add another ip address range as a secondary address range.

for example:

interface f0/0

ip address 192.168.0.1 255.255.255.252

ip address 192.168.0.10 255.255.255.252 secondary

and also this range has to be added in the routing protocol.
