I never knew of such a command. Where can I find it documented?
It's standard Unix. A lot of the Unix stuff is in the RISC OS network
stack, because the stack comes from BSD Unix. I don't know whether
it's in the RISC OS documentation anywhere.
arp manages the data held in respect of the Address Resolution
Protocol. This data is cached, for I think 15 minutes, before being
requested again. I use it in conjunction with pinging the network
broadcast address to see what's visible. Mote however that Windows
systems don't respind to the broadcast ping. On this network the
broadcast address is 192.168.0.255, i.e. host number with all bits
set.
