hello,
I’d like to go to a website which support ipv6 only, and doesn’t resolve correctly on ipv4 (for various reasons)
I can’t do this on webpositive or other browsers on haiku.
According to the standards, ipv6 should be resolved first:
How could I achieve that?
AFAIK ipv6 support is not complete in Haiku, so expect dragons.
Best strategy I read to attract new users. Let’s spread the word that we have dragons. 
Yepp!
Dragons are more sympathetic than some Dragonov !.. 8D
( Sorry for this poor pun - I could not skip it ! :)) )
Do you have IPv6 configured? (there is no autoconfiguration or DHCPv6)
The other main issue with IPv6 is that Haiku doesn’t support Path MTU discovery (this also affects IPv4, but is a bigger issue with IPv6, particularly if you are using a tunnel for IPv6 connectivity)
You need an interface with a valid IPv6 address, indeed.
I can only say for WebPositive, in its case, the address resolution is done with the AI_ADDRCONFIG flag, so IPv6 will not be tried if there is no configured IPv6 IP on network interfaces, as documented here: Ubuntu Manpage: getaddrinfo, freeaddrinfo, gai_strerror - network address and service translation
After you have manually set up an address, things should work, but I have not done much testing. I think the other problems in the IPv6 stack have been solved, but I didn’t try it myself recently (I guess I should figure out how to set my machine with an IPv6 address, it would be nice if it could do it automatically)
I thought I had ipv6 when I’ve looked in the ifconfig or with some ping, but indeed I’ve just tried again with ping6 and it says “network is unreachable”. I don’t know what data to enter to configure ipv6…
These tickets need to be resolved for ipv6 support:
