Renumbering is possible, but you are missing in your list implications such as renumbering the DNS and making sure that the servers work with the old and the new addresses for some hours, interruptions in live session, etc., etc.

There’s on PA-ISP lockin in IPv6 unless you build your network stupidly. If you use DHCPv6 or SLAAC to assign addresses to the majority of your systems and static address your servers only, renumbering is relatively quick and not particularly painful. 1. Connect the new ISP and add the new ranges to the routers. 2. Add the new address range(s) to the servers. 3. Change your SLAAC RAs and DHCP servers over to announcing the new addresses 4. Wait until the old addresses are deprecated off the interfaces of all the clients. 5. Remove the old address range(s) from the servers. 6. Remove the old address ranges from the routers. 7. Disconnect the old ISP Personally, if I were running an SMB IT department, I’d much rather face the above 7 steps for each ISP changeover than the joys of ULA+NPTv6. OTOH, I’d probably just multi home in most cases, in which case, RIR /48 here I come, easy peasy, current policy. Owen On Sep 13, 2021, at 09:38 , Larry R.

With the mentioned routing issue not being sustainable however, my proposal is likely DOA. Thank you. From: Owen DeLong <o...@delong.com> Sent: Monday, September 13, 2021 9:00 AM To: Larry R.

I’m neither in favor nor opposed at this time, but the answer to the above question is pivotal to whether this proposal serves an actual need or merely panders to the idea of PI for everybody, which until we change our routing technology to separate locators from identifiers isn’t sustainable.
