Thanks Joe, I must've misunderstood other mailing list's discussions. I thought small-fry ISPs were forced to have only one upstream and only the biggies were able to have more than one. I mean to multi-home to many different providers and an IX or two just like I do today, BTW. Thanks for setting me on the right thought-path and apologies to the list for any confusion. scott --- jabley(a)ca.afilias.info wrote: From: Joe Abley To: surfer(a)mauigateway.com Cc: Subject: Re: [nznog] THE SKY IS FALLING ( was Re: IPv4 Exhaustion) Date: Tue, 28 Nov 2006 19:10:53 -0500 Scott!

Exactly. I NEED to multihome. I won't accept not being able to do that. No provider is going to be good enough that I trust ALL of my connectivity with them and no one else. That settles it right there. A protocol should not dictate my business practice.

You can multi-home in v6 in precisely the same way as you do in v4 if you're an ISP, under all RIR policies. This also goes for anybody who qualified for v4 PI assignments in the ARIN region (so, end users too, at least those who qualify for sufficient addresses to want to multi-home with PI v4 space). Other regions will presumably follow suit if their respective memberships want that to happen. The ability to multi-home using PA v6 space (as is commonly done in the v4 network) depends on deployed filtering practice. Currently, it doesn't work very well; however, if there was pressure from an actual customer base, it could well be that it would work more often. Neither of these require any additional protocol development or implementation effort, and both ought to be very familiar to anybody who is multi-homed using v4. Nothing until this sentence has had anything to do with shim6, for example. There are lots of arguments for why v6 won't/shouldn't/can't succeed as a replacement for v4, but multi-homing is barely one of them. Joe
