[arin-ppml] Proposal - Remove Initial Small Assignment Requirements for IPv6

[Owen DeLong]

I disagree…

Renumbering a wisely deployed network in IPv6 is _MUCH_ less overhead and much much easier (and faster) in IPv6 than it was in IPv4, even on large-ish scales.

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.
