    ARP ("Address Resolution Protocol") is used to determine a MAC address,
    given a request for an IP address. It is used between router and client
    (sort of "not routable by design")

    A decent router also has a significant amount of cache (to remove the
    transmission delay that an ARP broadcast would cause), but can still be set
    up badly (e.g. NTL in the UK)
