Definition

Subnet Mask

A subnet is the name given to a cohesive area of IP addresses. The first bits are identical, and only the last bit in each case is different.

Net masks have the following format: XXX.XXX.XXX.XXX/YY

  • XXX defines one byte each of the IP address (allowed values are 0 to 255)
  • YY defines the number of valid bits (allowed values are 0 to 32)

When subnet masks are created, the input values are converted so that simplified input is possible.

Note

When a host name is entered, it is converted to the corresponding IP address if possible. It is assumed that all 32 bits are relevant.

Use

Net masks can be the basis for defining locations (see alsoMaintaining Locations of IP Subnets).
