how to change ipv4 endpoint ?

[dominix]

hi everyone.
I have  a long time ipv6 address that I would like to move to a new server as I reform a old one.
the new server will have a different IPv4 addres, and I do not hacve any login regarding the assignment of the ipv6 address. however I remember it was from HE.
How do I do that ? do I need to register somewhere ?

thanks for you tips.

You will need your HE user name and password to change the endpoint.  You may recover your user name from the tunnel DNS name PTR record.

Use the routed /64 reverse.  Example:

0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.4.0.0.0.d.0.0.0.0.7.4.0.1.0.0.2.ip6.arpa. 1d IN PTR snarked-1.subnet.ipv6.he.net.
