Parameters
net: Specifies a NET as a dotted hexadecimal string in the X…X.XXXX....XXXX.00 format. The X…X
segment represents the area address, the XXXX....XXXX segment represents the system ID, and the 00
segment is the SEL.
Usage guidelines
A NET is a special NSAP address with the SEL being 0. The length of the NET is in the range of 8 bytes
to 20 bytes.
A NET comprises the following parts:
• Area ID—With a length of 1 to 13 bytes.
• System ID—A system ID uniquely identifies a host or router in the area and has a fixed 6-byte
length.
• SEL—It has a value of 0 and a fixed 1-byte length.
For example, a NET of ab.cdef.1234.5678.9abc.00 specifies the area ID ab.cdef, the system ID
1234.5678.9abc, and the SEL 00.
Examples
# Specify the NET as 10.0001.1010.1020.1030.00, of which 10.0001 is the area ID and
1010.1020.1030 is the system ID.
