Look Up a Domain's Address (A Record)
See exactly which IP address a domain points to right now.
How to use it
- Enter the domain without http, and without www unless you mean it specifically.
- Press Check.
- Compare the address shown against the one your host expects.
The A record is the link between a domain name and the IP address hosting it. When you move a site to new hosting this is the record you change — and checking it tells you whether the change has actually propagated or visitors are still reaching the old server.
The TTL shown tells you how many seconds browsers and providers cache the answer before asking again. Before a planned migration, drop the TTL to 300 a day or two ahead and the switchover becomes near-instant instead of dragging on for hours.
Frequently asked questions
Large sites spread traffic across several servers, and CDNs return different addresses depending on where you are. Multiple addresses is a sign of health, not a fault.
Because the old answer is still cached. Wait at least as long as the previous TTL. Our own results are cached briefly too, so give it two minutes before re-checking.
An A record holds an IPv4 address like 93.184.216.34; AAAA holds the longer IPv6 form. Most domains need A, and adding AAAA makes the site reachable over IPv6 as well.
