It's easier to remember the IPs of good DNSes, too. (lemmy.sdf.org)

If all that is true, then why do I still hate ipv6 so much.

[–] sep@lemmy.world 15 points 5 months ago

I assume the normal fear of unknown things. It is hard to hate ipv6 once you have equivalent competence in ipv4 and ipv6.

I'd bet it's this little bugger " : "

It is for me.

The : is ok. I dont struggle with the shortening part. I struggle the "everything else" part.

What is localhost now again...

Edit, remember you could use 127.0.0.1, but then it was changed to like 127.0.0.1......something....ff

So guess I was wrong :-) thanks for the info!

For me is because it’s so fucking slow. As soon as I disable ipv6 on every device it has better speeds.

IPv6 is trash.

[–] orangeboats@lemmy.world 11 points 5 months ago

Tell that to your ISP which has fucked their IPv6 deployment up. In my experience IPv6 is actually faster since it bypasses the IPv4 CGNAT.

On busy days my IPv4 connection can get as slow as 15KB/s, now that's trash.

[–] efstajas@lemmy.world 6 points 5 months ago (1 children)

Lol that's ridiculous. There's nothing about ipv6 that'd make it any slower

[–] frezik@midwest.social 2 points 5 months ago (2 children)

There's one practical thing. Routers have had years to optimize IPv4 routing, which has to be redone for IPv6. Same with networking stacks in general.

In theory, IPv6 should be faster by not having to do bullshit like CGNAT. There's every reason to think it'll match that advantage if we just make it happen.

In the USA, around 50% of Google traffic and 60% of Facebook traffic goes over IPv6. The largest mobile carriers in the US are nearly entirely IPv6-only too (customers don't get an IPv4 address, just an IPv6 one), using 464XLAT to connect to legacy IPv4-only servers. I'm sure we'd know if routing with IPv6 was slower. Google's data actually shows 10ms lower latency over IPv6: https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption

[–] frazorth@feddit.uk 1 points 5 months ago

That doesn't make it "trash".

[–] dan@upvote.au 2 points 5 months ago

Google's data shows that IPv6 is usually faster. Their metrics show an average of 10ms less latency over IPv6 in the USA and Canada: https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption
