Could someone explain this to me?
- swiley 5y agoA type DNS records are used for looking up IPv4 addresses, AAAA records are for IPv6. This effectively takes Reddit off of the IPv6 internet and is a bit of a step backward.
- Natsu 5y agoAAAA records are the type of DNS records for IPv6. I take this to mean that Reddit only has AA records (IPv4) addresses now.
- cassianoleal 5y agoNit: A, not AA records.
- voisin 5y agoLooks like it defaults to old.Reddit.com now?
- ComputerGuru 5y agoNo, the link that was submitted was (thankfully) an old.reddit.com link is all.
- decrypt 5y agoI thought "is back to being a legacy website" is referring to old.reddit.com. Had me excited for a moment.
- ComputerGuru 5y agoYou weren't the only one for sure!
- ComputerGuru 5y agoIn the world of the glue that holds the web together, A is a DNS record that maps a domain name to an IPv4 address. AAAA is a DNS record that maps a domain name to an IPv6 address. A website without an AAAA can only be used over IPv4. (The opposite is also true, a website like http://ip6only.me/ http://ip6only.me/ that has only an IPv6 AAAA DNS record cannot be reached over IPv4.) A user noticed that Reddit recently turned off its AAAA records, and posted asking why it was now an IPv4-only site.
- cassianoleal 5y ago> A website without an AAAA can only be used over IPv4. Nit: if IPv6 is still enabled server-side, it can be used over IPv6 but you can't rely on public DNS for discovery and may have to set Host headers manually.
- cassianoleal 5y agoReddit used to have an AAAA (DNS IPv6-equivalent of an A record). They deleted the record. Users have noticed and posted. > Yea, we found a couple of internal issues that need some debugging. Since it's a holiday week we decided to rollback. Better safe than sorry. > > It'll be back, don't worry. Nothing to see here, really.
- pronoiac 5y agoThey noted an issue with IPv6, and disabled it rather than troubleshoot it over the holiday weekend.
