DNS Lookup
Query DNS records for any domain. Supports A, AAAA, MX, TXT, NS, and CNAME record types.
DNS is how the internet turns a domain name like
example.com into
an IP address your computer can actually connect to. This tool queries the official records for
a domain — useful to confirm a website's address, see which email servers handle its mail, or
check whether a domain has set up the records needed for things like SPF or domain ownership verification.
Looking up DNS records...
What each record type means
- A — the IPv4 address(es) for the domain. This is the most common type.
- AAAA — the IPv6 address. Newer than A, used alongside it on modern dual-stack networks.
- CNAME — an alias pointing to another domain (often used when a domain is hosted on a service like Shopify or GitHub Pages).
- MX — the mail servers that receive email for this domain. Lower priority number = tried first.
- TXT — free-form text records. Mostly used for email security (SPF, DKIM, DMARC) and to prove domain ownership to services like Google.
- NS — the authoritative name servers — who's actually in charge of this domain's DNS.
When you'd use this
- Checking a website moved — see whether
example.comstill points to the IP you expect. - Debugging email — if mail isn't arriving, the MX and TXT records are the first thing to check.
- Verifying domain setup — services like Google Workspace, Shopify, or your registrar tell you to add a TXT or CNAME — this tool confirms it took effect.
- Curiosity — see how big sites organize their infrastructure: how many A records, which CDN, which mail provider.
A note on caching
DNS changes don't propagate instantly. The world sees the new value as resolvers' caches expire — sometimes minutes, sometimes hours. This tool queries from our server, so it reflects what the authoritative servers say right now; your home or office network may still see the old value for a while.
