IPvFoo author here. The problem is that there's no way to obtain the (hostname, ip) stream from Chrome/Firefox without requesting the "all websites" permission. In theory, browser vendors could define a narrowly-scoped permission that only reports (hostname, ip), or roll this functionality into the browser UI, but neither seems likely to happen. I made IPvFoo to promote IPv6 adoption, and wouldn't consider selling it…

To determine ipv4/6, do you need to send that hostname and ip off to somewhere to get a response? or can it be done locally without leaving the machine?

It's local. The webRequest API provides an 'ip' field with each request, and the hostname can be extracted from the URL. Once you have an IP address, just check for colons.

IPv6 is still pretty useless to most people... Actually for me it complicates my firewall rules and don't bring any benefits (yeah down-vote me and don't reply ...)

I don't understand what you mean by complicating firewall rules,except maybe that you now need to use IPv6 addresses instead of IPv4 addresses in some of the rules. It's not like NAT without a firewall gave any security in 2024.

Yeah, sure: managing both IPv4 and IPv6 on the same network is painful. Thankfully you can disable IPv4 locally and set up NAT64 on the router: most people won't even notice the change.

"Pretty useless" is nonsense; Google works on IPv6, and 41% of Google's users access it via IPv6 [1]. "Most people" is also not true: most internet users use Google [2] (those not accessing it via IPv6 probably can't).

Advantage: Not out of addresses.

We’ve been “running out of ipv4 space” since before i got a freakin us robotics modem.

Yes, and it's a pain in the butt for people who are trying to provision servers in 90% of the world

cool, but "read and change your data on all websites" is imho not worth the functionality. that seems ripe for takeover by some scammer.

Just read the source code.

Not good enough to protect against the kinds of attacks that OP is warning against. Chrome extensions update automatically and there have been many cases of extensions being purchased by malicious actors who modify the code to be spyware or adware.

You can download the current version and install it manually to get around that. If you do that and read the code you're probably safe.

As someone who grew up on IPv4, i will miss it, but the leap to 340 undecillion unique addresses is exciting in many ways so i think i can learn to live with this transition. If we ever need more than that, i can't even imagine what that future would look like.

I grew up with IPv4 (1.2.3.4) and I was expecting IPv6 to just be 1.2.3.4.5.6 with backward compatibility so that 1.2.3.4 would just be 0.0.1.2.3.4 and the 1.2.3.4 dude wouldn't need to change their address. And the IPv8 would be 0.0.0.0.1.2.3.4 whenever we need it, but probably not for a long time When I saw all the double-colons and slashes and monstrosities like f00f:00f:::ea//dead::beef/3 I just kept using IPv4.…

and people are wondering why v6 never took off...

Another person who does not understand IPv4. IPv4 isn't a text based protocol where IP addresses are parsed like DNS. It's a binary protocol where addresses are recorded in binary and adding more address space WOULD BE A BREAKING CHANGE.

That's not what GP said.

Of course IPv4 devices wouldn't be able to use IPv6 addresses, that would be impossible. But it is possible to "keep" IPv4 addresses, just make a.b.c.d to correspond 0.0.a.b.c.d.

So the problem is in the behaviour of the browser, but not the extension.

Read the code, don't update 'till you read the code, don't use the browser which knows better what is good for you.
