Fix your domain's A/AAAA DNS record so it resolves correctly

15 min Impact: high Effort: medium ✓ Scan-verified — no manual checkbox

The A (and AAAA for IPv6) record is the fundamental DNS entry that maps your domain name to the actual server IP address — this is the most basic building block of your site being reachable at all, and errors here mean total outages, not partial issues.

An A record points your domain name to an IP address. Without it, your domain doesn't resolve — no one can reach your site. This is the most fundamental DNS record.

How to fix it

1

Verify your A record points to your current server

Check via DNS lookup that the IP address matches your actual current hosting provider — a leftover record from an old host is a common issue after migration.
2

Add an AAAA record for IPv6 if your host supports it

Increasingly relevant as IPv6 adoption grows — check if your host provides an IPv6 address to add.
3

Confirm propagation after any change

DNS changes can take up to 48 hours to fully propagate globally — verify from multiple locations/tools, not just your own connection.

Common mistakes

After migrating hosts, the OLD A record sometimes gets left in place alongside the new one, or DNS caching makes it look fixed from your own location while other visitors still hit the old server.

How you'll know it's done

Your A record (and AAAA, if applicable) correctly points to your current, active hosting server.
