Re: Extend the Subnet

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Dear Richard,

Thank you for your advice.

Do you mean that if we continue to use Class C subnet, you recommend using
192.168.x.x ? If we determine to change to Class C subnet, is there any
valid address suggested (Just to make sure that it is a private address) ?

Thanks

You cannot extend the existing 192.17.1.x and 192.17.2.x subnets because
they are already at their maximum number of entries - extending the 1.x
subnet will start whacking addresses out of the 2.x subnet, and extending
the 2.x subnet will start whacking addresses out of the 3.x subnet so
those choices are out unless you are prepared to entirely move a range.

Anyway, I think your addressing scheme currently is illegal - 192.17.x.x
is a non-private address range, you should be using 192.168.x.x
addressing.

I am new to networking and would like to seek your advice.

We are using Class C and as the number of devices in the head office is
increased, we believe that it will reach the limit of 254 devices. It is
also get connected to 2 subnets in remote sites via routers.

One fellow suggests us to use 192.17.1.x/19. It seems that it is a Class
C network with Class B subnet mask.

I would like to know, in this way, the number of hosts is increased to
8046 but how should we configure the existing subnets. For instance, the
existing ones are using 192.17.1.x, 192.17.2.x and 192.17.3.x.
