(I'm sending this feedback here because Azure feedback via official channels is printed out and then fed directly into a shredder.)

Can you answer why -- for the love of God -- why Azure IPv6 networking is doled out in microscopically small /124 blocks (16 addresses)!?

The standard is a /64 at a minimum for residential connections, and /48 is recommended for most premises, particularly business connections. Azure could easily obtain a /32 for each of their regions, providing a very roomy 4 billion /64 scopes per data centre.

Right now, if I want to "embrace IPv6" and all of its advantages, such as a flat address space and the elimination of NATs, I will have to either:

1) Juggle a bunch of /124 prefixes and carefully allocate services to them. This is a load of fiddly scripting or manual work.

2) Probably be forced to NAT anyway!

3) Pay for addresses that ought to be too cheap to meter.

Sorry, I'm pretty far removed from low-level networking, on CDN team and fairly new at that. I'd have no idea who to ask.
