DNS Lookup
Query DNS records for any domain in real time. Supports A, AAAA, CNAME, MX, NS, TXT, SOA, SRV, and CAA record types via DNS-over-HTTPS.
IPv4 address
Quick examples
DNS Record Types
| Type | Full Name | Purpose |
|---|---|---|
| A | Address | Maps a domain to an IPv4 address |
| AAAA | IPv6 Address | Maps a domain to an IPv6 address |
| CNAME | Canonical Name | Alias pointing to another domain |
| MX | Mail Exchange | Specifies mail servers for the domain |
| NS | Nameserver | Lists authoritative DNS nameservers |
| TXT | Text | Arbitrary text: SPF, DKIM, DMARC, verification |
| SOA | Start of Authority | Primary nameserver and zone metadata |
| SRV | Service Locator | Location of servers for specific services |
| CAA | CA Authorization | Which CAs may issue TLS certificates |
What is DNS-over-HTTPS?
This tool uses DNS-over-HTTPS (DoH) to resolve queries through Google's public resolver at dns.google/resolve. Unlike traditional DNS over UDP, DoH encrypts the query inside HTTPS, preventing interception and tampering. Results reflect Google's view of the current DNS state, which may differ slightly from other resolvers due to caching.
Common Use Cases
- Verify email deliverability via MX records
- Check SPF / DKIM / DMARC TXT records
- Confirm domain propagation after DNS changes
- Debug CNAME chains and alias configurations
- Validate CAA records before TLS certificate issuance
