A Record Lookup

Find the IPv4 address(es) behind any hostname via its A record.

IPv4 addresses only. Need IPv6? Use AAAA via DNS Lookup.

How to read the result

An A record maps a hostname to one or more IPv4 addresses. Large sites return several (round-robin). A 404 means the name has no A record — it may be IPv6-only (AAAA) or an alias.

Example

google.com → 142.250.x.x, TTL 300s

FAQ

Why multiple IPs?

Load balancing. Clients pick one; all are valid.

No A record but site works?

It may be IPv6-only or CNAME-aliased. Check AAAA or CNAME lookups.

What is TTL?

Seconds resolvers cache the answer before re-querying.
