Re: Subnetmask Issues

Tech-Archive recommends: Fix windows errors by optimizing your registry

Getting close, but not quite right yet. The subnet mask defines how much
of the address defines the network. So with a 24-bit subnet mask, the first
24 bits are network definition and the remaning 8 define the host. So all
addresses beginning with 171.107.1 are in the same subnet, and you can have
254 of them from 1 to 254 . Zero and 255 are reserved. Zero is used to
define the subnet itself and 255 is a broadcast address.

To have two subnets of 254 hosts starting with 171.107, the third octet
would need to be different. For example you could use 1 and 2. Subnet one
would be the subnet 171.107.1 0/24 containing the host addresses
171.107.1.1 through 171.107.1.254 . The second subnet would be
171.107.2.0/24, containing 171.107.2.1 to 171.107.2.254 .
