ipv6 bind to single v6-address

[Arul Murugan]

Hi Florian,
               Listen-on-v6 Specifies the ports on which the server listens
for incoming
queries sent using IPv6. The server does not bind a separate socket to each
IPv6 interface address as it does for IPv4. Instead, it always listens on
the IPv6 wildcard address. Therefore, the values allowed for the
address_match_list argument to the listen-on-v6 option are:
• any
• none
Multiple listen-on-v6 options can be used to listen on
multiple ports. For example:
listen-on-v6 port 53 { any; };
listen-on-v6 port 1234 { any; };
To make the server not listen on any IPv6 address, specify
the following:
listen-on-v6 { none; };
If the listen-on-v6 option is not specified, the server does not listen on
any IPv6 address.

Regards
Arul
