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.

172 Tunneling means encapsulating data of one protocol type within
173 another protocol and sending it over a channel that understands the

176 networks over an IPv4-only path.

202 The destination address is still the primary routing key, so mixing
203 normal and source prefix specific routes in the same routing table
204 may sometimes lead to unintended routing behavior. This can be
205 avoided by defining different routing tables for the normal and
