I was reading http://www.pcstats.com/articleview.cfm?articleid=1427&page=3 and it says:
Sets with the value of 0 indicate the host portion of the IP address, and sets with the value of 255 indicate the network portion. For example, with an IP address of 169.254.73.160 and a subnet mask of 255.255.0.0, the network portion of the address would be 169.254, and the host portion would be 73.160. This means the computer assigned this address is host 25 within network 192.168.0.
Where does that 25 come from?!
