To celebrate the eight-year anniversary of World #IPv6 Launch Day, we're sharing a graph of the uptake of IPv6-capable #RIPEAtlas probes in the last five years along with their location in our service region - they mark 42,6% of the currently active probes!
Hey, @madebygoogle@twitter.com, are you aware that #Chromecast does not work on an #IPv6-only network?
No matter whether there is NAT64 or not, the device keeps saying „try restarting your router“ 😠
RT @sjmsteffann@twitter.com
For those needing access to public @github@twitter.com repositories from #IPv6 only machines, you can use http://github-v6.com instead of http://github.com, like https://github-v6.com/netbox-community/netbox.git/.

I have been testing #IPv6 roaming while Corona-stranded in 🇷🇴, using SIM cards from 🇵🇱 Orange, 🇸🇪 Tele2 and 🇳🇴 Telenor.
The results, in short:
🤷♂️ Digi
✅ Orange
✅ Telekom
❌ Vodafone

Dear @GCPcloud@twitter.com, I have delayed my database upgrade on your platform for a few years hoping this lack of #IPv6 would be fixed by now. Sadly with only weeks left before a mandatory upgrade, I'm executing a #DOWNGRADE from v6-only to v4-only. Not cool! Yours sincerely, an #IPv6 user

Because some people manually disable #IPv6, the @ubuntu@twitter.com @nginx@twitter.com package maintainers decided to stop Nginx from listening on [::]:80 by default.

Has any one performed a packet loss, jitter and performance on MAP-T and MAP-E vs dual stack, NAT64/DNS64, or 464XLAT? #IPv6

You are my valentine; you bring me pleasure.
Your sheer range of addresses; so vast to measure.
Make this day one you’ll treasure,
and deploy #IPv6; a protocol for ever and ever.

Today: thinking about adding #SNI support to @openssh@twitter.com to add #proxy support for SSH. This could enable #IPv6only VMs to be reachable via SSH from the legacy Internet. #IPv6 https://lists.mindrot.org/pipermail/openssh-unix-dev/2020-January/038124.html

#Netflix a #IPv6 tunel = blokování šesti /48 IP rozsahů, aby to vůbec fungovalo. To jsem zvědav, co jsem si všechno zablokoval.

Google, one of the leaders in #IPv6 adoption, has no internal VPN that would support IPv6. That explains why so many ChromeOS features are broken on IPv6-only.

Less than a 100, but how many?
31.
@ripencc@twitter.com allocated 84 of those yesterday.
My last guess on a run-out date? Monday.
Have you deployed #IPv6 yet?

It’s happening! Less than 100 /22 IPv4 equivalents are left to allocate. Meanwhile the waiting list got released. #RIPENCC #IPv4 #IPv6 https://www.ripe.net/manage-ips-and-asns/ipv4/ipv4-waiting-list

People keep asking, what #IPv6 prefix size to use where on my network.
While guiding some network operators at #ngnog2019 I gave the recommendations on the board.
