Private ones usually do. (outgoing)

Corporate ones sure don't. Even outgoing HTTP is passed through proxies on most bigco networks I've worked at.

Yes. But I don't think that corporate firewalls matter when it comes to user adaption. If you need to work with SCTP in your company, you'll get your firewall rule, if not you don't.

If they want to only allow proxied HTTP, that's their decision and developers should respect that, and not mask everything under HTTP. Their administrators made a substantial effort to forbid everything, why would honest person try to overcome their effort?

Home routers is another matter, home users don't make conscious decision about it, but in my experience UDP works just fine (because a lot of games use it) and it should be good enough for any protocol.

What if I want to use my router to block telemetry domains? Or other malware sites? It’s looking like the only way forward is running my own CA to mitm all encrypted traffic.

That seems superior anyway - you could keep blocking domains even when you're on the go.

Easier approach is to use your own DNS server and blacklist those domains.

That graph has a couple doglegs that make it look exponential. The last dogleg was January 2015. And since then it’s been linear (with a little stall this month) at about 5% of the Internet converting per year. That’s another 15 years to convert the rest, unless there’s a new dog leg up. Also percentages don’t work the way humans think they do. Especially when the number of devices is constantly climbing. That may ju…

Agreed. I say IPv6 is inevitable, but it's not like the IPv4 addresses will expire. The economics going forward will be interesting. I've seen some low-end VPSes charge a lower rate for machines that are IPv6-only.

Cloudflare enabled domains can tunnel ipv6-only hosts for ipv4 clients.

You can tunnel SCTP on top of UDP. Port 9899. https://www.ietf.org/proceedings/48/I-D/sigtran-sctptunnel-0...

This is an improvement --- it was dumb of SCTP to try to claim a top-level IP protocol for this --- but only marginally, since lots of firewalls won't pass traffic on random UDP ports either.

Why was that dumb of SCTP? What should it have done instead?

This is just depressing. Sure, sell us out to big corporations by not implementing proper features in protocols like HTTP/2 so we can get tracked for decades to come. Yet, represent freedom by yet another cool way to "fool" governments. When historians look back at what happened to the Internet, or even society, they are going to find that organizations like the IETF was to busy with romantic dreams of their own grea…

What features are missing that should be implemented?

Support for Client Certificates.

Not the OP, but omitting support for SRV records in HTTP/2 was a terrible missed opportunity, as I’ve written about here before: https://news.ycombinator.com/item?id=8404788 https://news.ycombinator.com/item?id=8550133 I quote myself: “ It really is no surprise that Google is not interested in this, since Google does not suffer from any of those problems which using SRV records for HTTP would solve. It’s only users w…

I would also like to see SRV record support in HTTP/2 but IIRC Mozilla did some telemetry tests and found out that a significant amount of DNS requests for SRV records failed for no reason (or probably for reasons mentioned in this submission). Unfortunately I can't find a source link for that claim right now.

You, as a user, absolutely can. An ISP or network administrator who does not control the endpoints, on the other hand, cannot, by design. That's a feature.

What if I want to use my router to block telemetry domains? Or other malware sites? It’s looking like the only way forward is running my own CA to mitm all encrypted traffic.

Which will fail if apps check public keys manually, and is also not very efficient. I think we'll need to patch applications directly, but the good news is that since many people will need this, those patches will probably be developed.

Can I? On Android, apps now can decide if they want to accept user-installed CAs, or not. So if an app is hostile (say, all the Google apps), then I have no way to intercept their traffic anymore.

You can patch the app using apktool/smali or even use JTM[0], but I prefer just blocking their traffic using iptables.
