Note that ARIN NRPM 4.10 now requires the requested range to be used exclusively for IPv6 transition and not anything else.
As for full table, several providers I recommended in the original post are able to do a full table for less than $10/month. You can also join an IX and ask nicely for transit from other members. Some may even offer you free transit the moment you join.
Thanks, I'll poke around a few and see which looks best! A bit more than Vultr but well worth it for a full table.
Anything dual stack (dns, http, smtp etc.) is considered transitional. The only reason they say "exclusively" is so you technically have to give it back once its no longer used for that purpose. This is distinct from IPv4 blocks from the open market or the waiting list that you can sit on or sell if you no longer need them.
For most non-4.10 allocations only your original request needs to have been in good faith, after that utilization only factors into new resource requests.
For 4.10 the community wanted more restrictions to maximize availability for new networks.
10% is having my own looking glass was significantly faster and easier for me to use. But I probably wouldn't have done it all just for that, it was just fun to mess with.
In regards to peering the Vultr VPS option allows dirt cheap VPSs to peer so I'd recommend checking them out first.
Question to the crowd: what's a cheap good way to get a peer for full tables? Vultr is restrictive on that, sensibly so, but it was nice/fun having my own looking glass. I used to have it with a $150/m quarter rack Colo but after my home internet went 5 gig symmetrical it seemed like a massive waste to maintain a remote Colo so I dropped that.
