Appendix D: Subnet Mask Table

Below is a subnet mask table, which provides the following information:

1.Subnet mask expressed as a dotted decimal.

2.The number of total subnets along with the number of total hosts per subnet.

3.The network number, the IP address range, and the corresponding broadcast address.

This netmask table only shows possible subnets of a Class C address. For more information about TCP/IP and IP routing we recommend “Internetworking with TCP/IP” by Douglas Comer, Prentice Hall, 1995.
