Re: [IPv6] Question regarding expiration of /64 leases I should also mention you can always announce a ULA for devices like printers. Most stacks should prefer the the global address but so announcing a second ULA prefix shouldn't be a problem. |

1 edit | Wouldn't that still cause problems for devices that require internet connectivity?
Example scenario:
For whatever reason, your leased prefix expires. Your router pulls a new prefix, but majority of your devices on your network are still addressed with the old prefix. So now you're in a situation where all of the devices on your network need to be told to pull new addresses from the router which will be publishing the new prefix if prefix delegation is set up correctly. Manual intervention would be required to get majority of devices to pull new addresses in the new prefix.
To me, it sounds like there would be pretty big problems if something like this were to happen on a large network. |

kudos:3 | yes, that's why static addressing would be prefered in the long run. |

It is possible to actively retract prefixes by announcing them with zero lifetimes. Whether your local advertisement daemon is smart enough to manage all of that when your assigned prefix changes would be an interesting test. |

It would be to check to see if the RA implementation is buggy or not. |
