Nope, ARP is gone. But it gets a replacement as a part of IPv6, instead of ARP being an addition to IPv4. http://itkia.com/how-to-arp-a-in-ipv6/ http://www.tcpipguide.com/free/t_TCPIPIPv6NeighborDiscoveryProtocolND.htm
I have a question about how IPV6 interacts with the switches in the local network. Right now, my sub $50(US) gigabit switch from any of several vendors keeps an arp table to determine which switch port a message will use. With the huge address space available with IPV6, how is that going to work, and when am I going to get a cheap soho switch that can handle IPV6?
The switch will continue to operate using the MAC# of the client interfaces. The switch doesn't care about IPv4, IPv6, or IPX for that matter [unless you enabled vLANs or managment features - which is a different issue].
The switch does not maintain an "arp table". It maintains a list of MAC#s it has seen on each port.
