	Upgrade.

	Good.

% netstat -na | grep -w 53
tcp46      0      0  *.53                   *.*                    LISTEN
tcp4       0      0  130.155.191.236.53     *.*                    LISTEN
tcp4       0      0  127.0.0.1.53           *.*                    LISTEN
udp46      0      0  *.53                   *.*

%

	'netstat -na'  show all (a) the sockets numerically (n).
	'tcp46/udp46'  accept both IPv4 (mapped) and IPv6 connections.
	'tcp4/udp4'    accept only IPv4 connections.
	'tcp6/udp6'    accept only IPv6 connections.

	If you tell dig to use a IPv6 address that is what it will use.

	I have no idea what 'Bouncer' is.
