If you're on Comcast business, there's no real implication on turning off IPv6.

Any sites you use that are exclusively available only via IPv6 will stop working, but due to slow adoption of IPv6, that list of exceptions is quite small. IPv6 adoption is big in China, but even then the major services themselves are available over IPv4. (Weibo.com doesn't even advertise an IPv6 AAAA DNS record, so the things I read about IPv6 adoption in China may be overstated.)

There are, of course, exceptions. There are a number of intentionally ipv6-only test sites like https://ipv6.google.com that won't work. Things like Google.com which are available over both IPv4 and IPv6 will degrade gracefully if you turn off IPv6 on your mac, and just connect over IPv4.

Google found this company offering ipv6 support.

What I'd really like is a vpn that gives me an ipv4 address and an ipv6/64 so I can have my router do the vpn and route my whole network through a vpn by only configuring one computer.

No VPS supports IPv6?

I can think of a few off the top of my head that do:

* Linode

* Vultr

* Tilaa

* DigitalOcean.

I'll provide you with a VPN that supports IPv6. Email address in my profile.

EDIT: And the full implications of disabling IPv6 are approximately nothing.

Why the secrecy? Many of us would like to know. It's fine if it's pitching a product that you are making. We would like to sign up.

There's no secrecy, there's no product yet. I just already operate a VPN for my own use, and could easily do so for others. Maybe a product would come out of it, maybe not.

Who are you? How do I know you're not logging my traffic and selling it?

It sounds like you're in the UK - I'm a US person, if I give you my traffic, what will courts say about my expectation of privacy?

I'm James Stanley. I blog at http://incoherency.co.uk/

I already operate https://smsprivacy.org/ which is essentially a VPN for SMS.

I don't have any way to prove I'm not logging your traffic, but I am a big believer in privacy and promise not to. If you don't trust me, you don't have to use it.

> How do I know you're not logging my traffic and selling it?

The same way you know any VPN company isn't. You just have to take their word for it.

Why is the word of a fly-by-night VPN provider any better than a HN poster?

According to the Supreme Court you don't have any expectation of privacy in information given to a third party so whether the VPN is in the US or not does not matter.

That's an oversimplification of the Third-Party Doctrine, particularly as applied today.

DiitalOcean supports IPv6.
