I have configured a server with Gentoo 64 bits that it has IPv4 and IPv6 and they are working well. But I don't know how specify the IPv6 of the server in /etc/hosts file. With or without "/64" final?:

...
ipv4.XXX.XXX.XXX nsXXXXXXX.ip-XXX-XXX-XXX.eu 
ipv6:XXxX:XX:xxxX::/64 nsXXXXXXX.ip-XXX-XXX-XXX.eu
....

or

....
ipv4.XXX.XXX.XXX nsXXXXXXX.ip-XXX-XXX-XXX.eu 
ipv6:XXxX:XX:xxxX:: nsXXXXXXX.ip-XXX-XXX-XXX.eu
....

?
