Subneting question

[Leonardo Pena Davila]

Hi on my network a have this segment 167.175.60.0 with mask 255.255.255.0.

Can I take this segment to do something like 167.175.60.220 mask 255.255.255.252.

Can I have this segment with both masks?

thanks

regards

Hello,

overlapping address spaces on the same router are not allowed. If you actually configure this:

interface FastEthernet0/0

ip address 167.175.60.1 255.255.255.0

and then try to configure:

interface FastEthernet0/1

ip address 167.175.60.221 255.255.255.252

the router would tell you:

167.175.60.220 overlaps with FastEthernet0/0

HTH,

GP

You cannot normally have two overlapping subnets on the same segment at the same time - at least not in the same router. Even in different devices, having an inconsistent mask is quite problematic. 167.175.60.220/30 is a subset of 167.175.60.0/24, so that would not be allowed.

But perhaps I misunderstand the question - could you go into a bit more detail please.
