That is the address of his fido machine.
There are also 2001:470:70:bf5::1 and 2001:470:70:bf5::2. Note the '70' instead of the '71' in the third position. Those two addresses are the end points of his he.net tunnel. They both ping from here as well now. Since his tunnel does not end on his router, but on his fidonet system, his binkp server may also answer on the address of his tunnel end point.
His setup is a bit unusual. Most have the tunnel terminate on their router, so that IPv6 traffic can be routed to all devices on the LAN.
Andrew, why do you not have the tunnel terminate on your router? Does your router not support 6in4 tunneling?
