IPv6 support

Open tambry opened this issue 6 years ago • 5 comments

The site is inaccessible over IPv6.

Any idea why?

Because the site has no AAAA (aka IPv6) DNS record. As such, if only IPv6 connectivity is available, then the OS has no IP it can actually connect to.

For fixing this, one should first check their host's IPv6 support. Any good server host these days has full IPv6 support.

The host is https://zeit.co/now; the underlying deployment is at https://sapper-hacker-news-fiurujojqb.now.sh/top/1, is that accessible over IPv6? (Also, how can I test whether it is?)

The underlying deployement isn't accessible over IPv6 (nor is the host's website). IPv6 accessibility can be tested with something like this (but you'll find plenty of others, when you google). For checking DNS propagation you can use Google's DNS query tool (do note the TTL).

It's possible that your host has no IPv6 support at all, as I can only see a single subdomain of zeit.co, which is IPv6-accessible. It's probably a good idea first to contact them. Though zeit.co seems to use GCP, which only has IPv6 support for load balancing (worth a vote), but not instance-level IPv6, so it might not be even feasible for them.
