IP Router table Records (Response)
The number of IP router table records specified in the number of records parameter is returned. The total num-
ber of bytes in the IP router table records is calculated as the number of records × 8 bytes/record. The configu-
ration of the 8 bytes of data in each record is shown below.

The network ID from the IP address in hexadecimal. The network ID part corresponding to the address class
(determined by the leftmost 3 bits) set here, is enabled.
Router IP Address
The IP address (in hexadecimal) of a router connected to a network specified with IP addresses.

If the IP router table contains fewer records than the number specified in the number of records parameter, all
the records contained in the IP router table when the command is executed will be returned and the command
execution will end normally.
