[Opensim-dev] IPv6 (Ai Austin) Fred Beckhusen

[Fred Beckhusen]

One of the purposes of a router is to do the NAT between IPV6 and IPV4 
and vice versa.  IPV4 can always be made into an IPV6 by making it hex 
and adding leading ffff digits.

I think one way to support it would be to put the server on a router 
inside a LAN.  The  Dyn DNS for Dreamgrid essentially works that way.  
On Registration, it takes IPV4 as input  via CGI, and uses Perl's 
ip_transform to make an IPV6.  For example, 68.38.95.213 = 
::ffff:4426:5fd5.  It saves both IPv4 (A record) and IPV6 (AAAA) in a 
table.  A DNS request does a simple query of the table and returns the 
above IPV6 when asked for a AAAA record.  The router then sends that to 
the PC to the correct IPV4.
