What Is an A Record?
An A record is the most basic DNS record type – it maps a hostname to an IPv4 address. When a browser or any other client resolves a domain, an A (or AAAA) record is the record that ultimately answers 'where do I connect.'
- •Pointing a domain or subdomain at a web server's IPv4 address
- •Confirming a hosting migration or DNS change actually took effect
- •Diagnosing why a hostname 'doesn't work' – a missing or wrong A record means it never resolves anywhere
Example
192.0.2.10
A single IPv4 address returned for the queried hostname.
Things to Know
Multiple A records means load balancing
It's normal for a domain to return several A records at once – clients typically pick one (often round-robin), spreading traffic across multiple servers.
A record vs. CNAME
A hostname can have an A record or a CNAME pointing elsewhere, but not both at the same name – if you expected a CNAME here and see an A record instead, check whether the setup uses CNAME flattening at the DNS host.
Next Steps
CNAME Record Checker
Check whether a hostname is aliased elsewhere instead of resolving directly.
CNAME Record Checker →Frequently Asked Questions
Is this A record checker free?
Yes – look up A records for any domain, for free, no signup required.
What's the difference between an A and an AAAA record?
A records return IPv4 addresses; AAAA records return IPv6 addresses. A domain can (and increasingly does) publish both for the same hostname.
I just pointed my domain at a new server – why is it still showing the old IP?
DNS changes take time to propagate, bounded by the record's TTL. Some resolvers and ISPs also cache slightly past the stated TTL.
