Hello,

does anyone work on a real ARP implementation? I mean, one which can
handle multiple protocols for link level and user protocol?

No, FDDI does not count: it seems to masquerade as Ethernet for ARP
purposes. 

ARCnet doesn't count either; I didn't implement it yet ;-)

I guess somebody might be working on IPv6 and implementing a real ARP
code for that, so I thougt it would be better to ask first.
