DNS Lookup
Query A, AAAA, MX, TXT, NS, CNAME, and SOA records at once.
Query a Domain's DNS Records
Enter a domain and this tool queries its DNS for the most useful record types at once — A, AAAA, MX, TXT, NS, CNAME, and SOA — and shows every value it finds, grouped by type.
Record types explained
- A / AAAA — the IPv4 / IPv6 addresses
- MX — mail servers, with priority
- TXT — SPF, DKIM, verification records
- NS / CNAME / SOA — delegation and zone data
Why look up DNS?
DNS records control where your domain points and how email is routed. Checking them helps you debug downtime, verify email authentication, and confirm changes have propagated.
How DNS resolution works
When you query a record, a resolver walks from the root servers to the domain's authoritative nameservers to fetch the answer. This tool performs that lookup server-side and returns the records exactly as the authoritative servers report them.
Propagation note
DNS changes are cached for the length of each record's TTL, so a freshly changed record can take minutes to hours to appear everywhere. If a value looks stale, give it time and check again.
