ip <subcommand>

     These commands are used for the Internet Protocol service.


    ip address [<addr>]

     Display or set the default local IP  address.  This  command
     must  be  given before  an  'attach' command if it is to be used
     as the default IP address for the interface.

    ip heard

     Display the ip-heard list. This shows the recently heard tcp/ip
     systems. See also the 'ip hport' command.


     
    ip hport [<iface>] [on | OFF]

     Display or set the ip-heard facility.  If no argument is given,
     show the interfaces on which ip-heard is currently active. If
     <iface> is given, shows the status of the ip-heard flag for the
     given interface. If <iface> <on|off> is given, it will set the
     flag on or off.   Default is off.
     
     If this flag is on, ip heard frames will be logged in a table.
     This table can be shown with the 'ip heard' command or with the
     nodeshell 'IHeard' command.  Ip-heard logging on ax.25 interfaces
     logs all ip stations heard on the port, even if the system wasn't
     directly involved in the ip activity.  For non-ax.25 interfaces,
     only ip frames that we were actively involved in (i.e. that we
     routed) are logged. (this difference is due to code internals)
     
          ip hport port1 on


    ip hsize [n]

     Display or  set the maximum size of  the Ip heard table. 0 means
     no limit.  Default=8
     

    ip rtimer [<seconds>]

     Display or set the IP reassembly time-out.  Default = 30 seconds
     

    ip status

     Display Internet Protocol (IP) statistics, such as total packet
     counts and error counters of various types.

    ip ttl [<hops>]

     (B)  Display or set the default time-to-live value placed in each
     outgoing IP datagram.  This limits the number of switch hops the
     datagram will be allowed to take.  The idea is to bound the
     lifetime of the packet should it become caught in a routing loop.
     You should make the value slightly larger than the number of hops
     across the network you expect to transit packets.  The default is
     set at compilation time to 255, the official recommended value
     for the Internet.
