Subnetmask to Subnetmask

Hi,

I have ip's range 200.10.10.1 and I can make subnetmask different to interfaces lan's

For example, eth0 200.10.10.1/255.255.255.252,

eth1 200.10.10.5/255.255.255.192 and so.

tks.

Re: Subnetmask to Subnetmask

Not exactly. Consider the enter network first. In this case, 200.10.10.0 - 200.10.10.255. If you use a mask such as 255.255.255.192 you have broken the network down into ranges 0 - 63, 64- 127, 128 - 191, 192 - 255. From there you can use a longer mask, such as 255.255.255.252 to break down one of the subnets into smaller subnets. Once you do, the entire subnet is used. So if you apply .252 to a .1 address, the entire .0 - .64 range is subnetted as such. The other three are left to use or further subnet however you like.
