APPENDIX D: SUBNET MASK TABLE
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.
