VLSM for different subnets

[cisco-blue]

Dear all,

a basic question

can i use the listed ip schema for to different networks or i have to be subnet specific for network s wise

10.80.10.129-10.80.10.158 255.255.255.224

10.80.10.161-10.80.11.30 255.255.255.128

You have to use proper subnetting for this.

The first IP scheme is correct.

The 2nd one is WRONG.

then what could be the consecutive 2 subnets for a network of 120 hosts

The real problem is that your question cannot be understood.

[cisco-blue]

as the first networks subnet is ok, what could be the next two subnets for network of 120 hosts with vlsm

"as the first networks subnet is ok, what could be the next two subnets for network of 120 hosts with vlsm"

10.80.10.192 - 10.80.10.254 255.255.255.192

(note you can't use 10.80.10.161 - 10.80.10.191 because of the way the bit boundaries work)

10.80.11.0 - 10.80.11.63 255.255.255.192

so those are your next 2 subnets if you only want 2 subnets and they must cover 120 hosts. You cannot however use just one prefix/subnet mask as you have tried to do, you need to have the 2 separate prefixes/subnet masks.

As Paolo has said your question doesn't make a lot of sense. 2 consecutive networks for 120 hosts could be

10.80.10.0 - 10.180.10.63 255.255.255.192

10.80.10.64 - 10.180.10.127 255.255.255.192

but then again it could be many other combinations as well.

One other thing. I very rarely comment on ratings but i fail to see how someone can be rated a 2 when the question is so unclear. Having checked some of your other posts it appears that 2 or no rating at all is what you tend to give.

Please show some appreciation for the efforts of the many unpaid volunteers on these forums.

It's all about love, rated Jon and the other fellow.

[Jon Marshall]

Agreed - rated :-)
