The subnet mask can be determined by the IP address. The subnet mask is typically represented in the form of a four-octet number, such as 255.255.255.0. The first octet of the number indicates the number of bits used for the network portion of the address, while the remaining octets indicate the number of bits used for the host portion of the address. To calculate the subnet mask from an IP address, simply convert the IP address to binary, count the number of bits in the network portion, and then convert that number to decimal. For example, if the IP address is 192.168.1.1, the binary representation of the address is 11000000.10101000.00000001.00000001. This address has a network portion of 24 bits, so the subnet mask would be 255.255.255.0.
