Subnetting

Hi,

I am using LAN addr range 192.168.1.0 mask 255.255.255.0

How can i create a subnet having a range of 192.168.1.1-60 and 192.168.1.61 -  ?
Need to specify such a range with its subnet for routing.

Thanks

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 http://www.subnet-calculator.com/ or http://www.subnetmask.info

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).

Hi,

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 192.168.1.1-60 and the other 192.168.1.61 -  xxx or perhaps having other subnets?

Thanks

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

192.168.1.0 /24
192.168.2.0 /24
192.168.3.0 /24

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