That's not really true anymore. I've used a connection with both IPv4 and 6 for the past two years. There's a number of times where my stuff magically works, whiles others have issues, because my traffic is mostly over IPv6. Not once have I had an issue because my setup is dual stacked.

This is still true for ISPs that don't monitor their IPv6 connectivity. I was forced to disable IPv6 recently because of this: https://www.reddit.com/r/ipv6/comments/1nf3ytq/how_do_i_comp... And before you say "change the ISP": Globe is the only one that does not refuse to provide services to foreigners and does not lock you up into a 24-month non-cancellable contract, which is longer than any available non-resident…

That's not really an IPv6 issue, but an ISP issue. My old ISP didn't monitor anything and relies on customers to call them up and explain that their connection is down. Sometimes tell them that their connection to entire towns are down, because they don't know.

I'm fairly fortunate that my ISP not only offers IPv6, but also knows how to run their network. Denmark has plenty of ISP that doesn't provide IPv6, don't know how to run a network or some many cases both.

I'm surprised at how negative HN as a whole is on VPNs. The argument seems to go that VPNs don't really give you much privacy. I disagree. I don't think they give absolutely privacy but there are benefits. As soon as you use a service in another country, it greatly complicates anyone trying to pierce that veil. A US shield can be pierced by John Doe warrants, FISA warratns, pen registers and so on. Some of these opti…

It's because the primary function of VPNs isn't privacy, it's to connect to a remote network and treat it as your LAN. Any privacy or security stuff is completely orthogonal.

Lots of things will break if you disable ipv4, including my work provided zscaler windows laptop (and not break in the good way where it fails open when you block traffic to zscaler nodes on your router) Very little will break if you disable ipv6

A lot of stuff breaks when you run Zscaler.

Absolutely, yet it's a requirement for many people.

As surveillance of social media ramps up, either by the government or by angry mobs, they're rapidly growing to be essential to use any unencrypted platform.

I encountered this with different VPN provider. Probably many more have this issue.

SwissVPN provides a /64.

Do they allow inbound ports?

Yes, all inbound ports are open.

If you can't see your VPN's source code, you can almost safely assume that they're broken in some way.

I have no idea why it seems to be so hard for VPN providers to get IPv6 right. The technology has been here for ages. Also, unlike physical ISPs, VPN providers have no other way to differentiate from each other but getting this sort of things right, so one could except them to be motivated, but no.

You are correct: "Kape Technologies is a United Kingdom-based cybersecurity software company. Kape owns VPN services and cybersecurity tools, including CyberGhost, Private Internet Access (PIA), ZenMate, ExpressVPN, and Intego." https://en.m.wikipedia.org/wiki/Teddy_Sagi#Kape_Technologies

Yes, I missremembered. It was bought by Isreali after all. I dont think my point is affected by this however. And I feel quite illiterate right now. I somehow managed to misread both your comments twice

Also Kape was formerly known as Crossrider and had alleged ties to shady apps in the past.

If you can see it you can also almost safely assume it’s broken in some way.
