Every so often an [IPv6] router is supposed to send out Router Advertisements saying what [IPv6] range(s) should be used on this subnet allowing a host to autoconfigure itself by appending it's [MAC] address to the [IPv6] address and using that. So it's kinda like a built in [DHCP]. |

Some gotcha's |
| |
|
4 |
* You need to configure linux boxen to send RouterAdvertisements, either by running radvd(8) (__R__outer __Adv__erisement __D__ameon) or by using zebra(8) or the like. |
| |
|
5 |
* You don't want to [DHCP] routers, so if you forward packets you aren't allowed to auto configure yourself. Kinda makes sense. |
| |
|
6 |
* You don't want to [DHCP] servers, so machines that run services should be manually configured with an IP address, if they aren't, they will auto configure themselves an address. |
| |
|
7 |
* Router configuration doesn't send out [DNS] servers or anything like that. I guess you're supposed to use AnyCast, except I don't know of anyone doing [AnyCast] [DNS] serving. |

Other than that, it means that desktop machines and the like just plugin and work, no configuration necessary. Very cool. |

Here's a page about how to configure RouterAdvertisements on debian, (although it's not very Debian specific): http://people.debian.org/~csmall/ipv6/setup.html |

Don't worry about your [IPv6] boxes having several IP addresses per Interface. [IPv6] enabled box collect them like stamps. |
