Description Sylvain BERTRAND 2008-03-26 09:22:54 UTC

Have an IPv6 only /etc/hosts and put that line:
::1 localhost
Compile and run the provided program, you will see that localhost is resolved to IPv4 127.0.0.1 and should be IPv6 ::1.

You can use a line like this in your /etc/hosts:
192.168.0.100 foo
Modify the name to resolve in the provided program, it will resolve ok, namely only IPv4.

If you do the same in your /etc/hosts with an IPv6:
xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx foofoo
Modify the name to resolve in the provided program, it will resolve ok, namely only IPv6

(BTW, the man page says of getaddrinfo says the first entry should point to the full canonical name which seems not to be the case, another bug?)
