10 This is complemental support for the IP version 6.
11 You will still be able to do traditional IPv4 networking as well.

13 For general information about IPv6, see
14 <http://playground.sun.com/pub/ipng/html/ipng-main.html>.
15 For Linux IPv6 development information, see <http://www.linux-ipv6.org>.
16 For specific information about IPv6 under Linux, read the HOWTO at
17 <http://www.bieringer.de/linux/IPv6/>.

19 To compile this protocol support as a module, choose M here: the
20 module will be called ipv6.
