This attribute is used when the connection needs a specific netmask number. Even though a client-based DHCP server often assigns netmasks to connections, in certain cases when groups of IP addresses aggregated by CIDR are distributed by the RADIUS server, specific netmasks may be necessary.

While this attribute can appear within an Access-Request packet, the server is not required to honor it, although it may do so.
