Absolutely not. Routers, OSes and applications still have much better support for IPv4 than IPv6.
Replacing large routers, fighting bugs and running pure IPv6 on internal networks is very expensive.
- fulafel 5y agoThere haven't been ipv4-only routers sold in such a long time that they've been retired from service by now. v6 was a new router feature something like 15 or 20 years ago (and same for operating systems).
- 2fastpost 5y agoIPv6 support is such a low bar. Now try IPv6 support and feature complete without bugs and get back to me. I’ll wait.
- goodpoint 5y agoAs 2fastpost wrote, basic IPv6 support is far from enough. Also I'm not talking about routers worth 50 euro/$, but DC and carrier grade, worth 500K euro/$
- fulafel 5y agoDo many reasonably recent 500k routers have bad ipv6 support? ISPs and many enterprise sized orgs have been running v6 for a long time, so it's not like it's a checkbox feature that hasn't had a lot of testing.
- goodpoint 5y agoThe question is: Do many reasonably recent 500k routers have more bugs or performance limitations around IPv6 than IPv4? Of course they do. They are hugely complex systems and troubleshooting and tuning is prioritized based on customers needs.
