DNS Lookup

Look up the DNS records for any domain. Enter a hostname to see its A (IPv4) and AAAA (IPv6) address records with their TTL values, resolved live through Google Public DNS over HTTPS.

DNS Lookup
Enter a domain name above to resolve its A and AAAA records.

What the DNS Lookup does

A DNS lookup translates a human-readable domain name such as example.com into the numeric IP addresses that computers use to route traffic. Every time you open a website, your device performs this lookup first — this tool lets you do it manually so you can verify exactly where a domain points.

Our DNS lookup queries Google Public DNS (dns.google) using DNS-over-HTTPS, so the results reflect authoritative, up-to-date records rather than whatever is cached on your local machine. It returns both A records (IPv4) and AAAA records (IPv6) together with the TTL (time-to-live) for each.

How to read the results

  • A — an IPv4 address the domain resolves to (e.g. 142.250.190.14). A domain can have several for load balancing.
  • AAAA — an IPv6 address for the same domain. If none appear, the domain is not yet reachable over IPv6.
  • TTL — how long (in seconds) resolvers may cache this record before checking again. Lower TTLs propagate changes faster.

Worked example

Input: google.com

A     142.250.190.14       TTL:300s
AAAA  2607:f8b0:4009:815::200e TTL:300s

The 300-second TTL means resolvers refresh this record every 5 minutes — typical for large services that shift traffic between data centres frequently.

Common use cases

  • Confirm a new domain or DNS change has propagated to the public internet.
  • Check whether a website supports IPv6 by looking for AAAA records.
  • Diagnose why a site loads for others but not for you (compare against your local resolver).
  • Verify that a CDN or hosting migration is pointing to the right IP.
  • Find the hosting IP of a domain before running a WHOIS or reverse-DNS check.

DNS Lookup — Frequently Asked Questions

What is the difference between an A record and an AAAA record?

An A record maps a domain to a 32-bit IPv4 address (e.g. 93.184.216.34). An AAAA record maps the same domain to a 128-bit IPv6 address (e.g. 2606:2800:220:1:248:1893:25c8:1946). Both can exist at once so the domain is reachable over either protocol.

Why do my DNS lookup results differ from what my computer sees?

Your operating system and router cache DNS records locally based on their TTL. This tool queries an authoritative public resolver directly, so it reflects the current published record even when your local cache is stale. Flushing your DNS cache aligns the two.

How long do DNS changes take to propagate?

Propagation time is governed mainly by the record's TTL plus caching along the path. With a low TTL (300 seconds) changes are usually visible within minutes; with a 24-hour TTL they can take a full day worldwide.
