I agree that the sipv6address is the way to go, but GM should do some
- If the calling GM is able to do IPv6, then try to see if there is a
sipv6address attribute first, and use it. If not, get back to the
- If the calling GM is not able to do IPv6, then always use the current
However, we have a problem there. If the connection to the ILS is done
over IPv6, the server will be able to check that the provided IPv6
address is correct, but not the IPv4 address. So, it means the client
could provide a bogus address. The problem is the same in the other
direction. An IPv4-only client could provide bogus IPv6 addresses.
That's the main problem. Anybody has an idea for that? (I don't think
double registration -ipv4 + ipv6 - is a valid solution here)
PS: we have to not add more options to the GUI, even for IPv6 as 90% of
the users won't use them and won't understand what it is.
