How can i create a subnet having a range of and -  ?
Need to specify such a range with its subnet for routing.

Do you want to split the whole class C into 2?  Then that would be the following:

2 Networks: - -
Subnet Mask (or /25)

4 Networks: - - - -
Subnet Mask: (or /26)

If you're looking for any other config just post.
Andrea already gave you perfectly good advice with configuration. But in your case, you'll want more no more than 4 subnets due to the fact you wanted at least 60 hosts in each subnet. Other ways to do, just let us know. (like if you need a network with 64, and another with 128)

If you want another config, look at or

But there are other links for subnet calculating as well.
I use WildPackets IP Subnet Calculator.  It's free and does the job well (but you need to know a few basic things about subnetting).

Im just interested to know why you would even want to do this? Just use 4 whole class C networks, 192.168.0/1/2/3 with a standard class C subnet. As they are non routable and effectively free  adress space i wouldnt worry about subnetting them.

For what its worth you sound like you are trying to make hard work / complicate things.

Hi Andrecoppini and masnrock,

Thanks for the nice illustration. Is there anyway to achieve my requirement of having a range of and the other -  xxx or perhaps having other subnets?

Lots of possible arrangements... but remember that the number of hosts in a subnet are powers of 2. 64 is the closest you'll get while having at least 60 (technically 62 when you factor out network address and broadcast address).

The best way to get those desired host numbers is to subnet useing 2 bits.

Take the original address - 255.255.255 (/24), add 2 extra bits giving you (26)

Your subnet ID's are then

your host ranges are - - - -

I belive this is the most suitable, and probably nearest match to what you want.

note; as mentioned above behind a NAT device there is no real need to subnet at all, you could use ; /24 /24 /24

with there standard 24 bit can then just use the host addresses you need.
