Querying DNS...
DNS Lookup
Queries DNS records for any domain name. DNS (Domain Name System) translates human-readable domain names into IP addresses and stores other records used for email routing, verification, and more.
Common DNS record types
| Type | Purpose |
|---|---|
| A | Maps domain to IPv4 address |
| AAAA | Maps domain to IPv6 address |
| CNAME | Canonical name, alias to another domain |
| MX | Mail exchange, where email is delivered |
| TXT | Text records, SPF, DKIM, domain verification |
| NS | Name servers authoritative for the domain |
| SOA | Start of Authority, zone configuration |
| CAA | Certificate Authority Authorization, which CAs can issue TLS certs |
| PTR | Reverse DNS, IP address to domain name |
| SRV | Service location (used by SIP, XMPP, etc.) |
DNS propagation
DNS changes propagate across the internet gradually due to TTL (Time to Live) caching. A record with TTL=3600 may take up to 1 hour to update globally. During propagation, different resolvers may return old or new values.
Privacy
This tool queries DNS via a browser-based API. The domain name is sent to a public DNS resolver (Google DNS or Cloudflare) to retrieve the records.
