If you want to reach the IETF site using only IPv6, you could use http://www.ietf.org.sixxs.org (see http://ipv6gate.sixxs.net for more about that) Notez bien that www.ietf.org has two hosts: $ host -t any www.ietf.org www.ietf.org A 132.151.6.21 www.ietf.org A 4.17.168.6 And if you have a problem with the site it might be very interresting to also include a traceroute to the host you are having problems with. Also a good debugger is to simply telnet to port 80 of the host or to do some tcpdumps. Greets, Jeroen -----BEGIN PGP SIGNATURE----- Version: Unfix PGP for Outlook Alpha 13 Int.
