Does anyone know how much IPv4 space is allocated *specifically* to cater to the fact that HTTPS requires a dedicated IP per DNS name?
Is that a statistically significant percentage of all the IPs in use?
I have no numbers, but my gut feeling is that there are a lot more eyeballs than web servers with lots of IPs.
Fair point. Though those are choked behind carriers who may well CGN them whether the eyeballs like it or not.
Wasn't there something going on to make HTTPS IP muxable? How's that coming?
SNI; RFC 3546
How fast could it be deployed?
The RFC is just shy of 10 years old, so that's like a baby compared to IPv6.
It is mostly deployed, but there's still a fair number of old clients that don't support it. WinXP+IE is probably the biggest fail, followed by Android < 3.0 and BlackBerry.
When you say "it is mostly deployed", what exactly do you mean? Is it layer 7 or 4? Does it live in libraries that can be upgraded behind users' backs? Or is it actually in the browser proper? Or are you just talking about the server-side of the equation? Cheers, -- jra -- Jay R.
