How to read a A record check

A records connect a hostname to an IPv4 address.

When to use this lookup

Use an A lookup after changing a website's server, moving a load balancer or checking whether recursive resolvers still hold an older IPv4 address.

Example

example.com A 93.184.216.34
Answer shape
One or more dotted-decimal IPv4 addresses, each with its own TTL.
Common failure
One authoritative server still publishes the old address, or a resolver is legitimately serving a cached copy until its TTL expires.

AAAA record, CNAME record

Troubleshooting checklist

  • Confirm the new address exists at the authoritative nameserver.
  • Compare answer TTLs before assuming a stale result is an error.
  • Remember that GeoDNS can intentionally return different addresses by region.
