DNS Lookup
Check DNS records for any domain — A, AAAA, MX, TXT, NS, CNAME
What is a DNS lookup?
A DNS (Domain Name System) lookup translates a human-readable domain name into its associated DNS records. These records tell browsers and mail servers where to connect when accessing a website or sending email.
DNS record types explained
A — Maps domain to IPv4 address. AAAA — Maps domain to IPv6 address. MX — Mail exchange servers for the domain. TXT — Text records used for SPF, DKIM, domain verification. NS — Authoritative nameservers. CNAME — Alias pointing to another domain.
How to use this DNS lookup tool
Enter any domain name in the search box above and press Look Up. The tool queries the domain's authoritative nameservers in real time and returns all current DNS records. Enter a bare domain (example.com) or include a subdomain (mail.example.com). The tool checks A, AAAA, MX, TXT, NS, and CNAME records simultaneously.
Common reasons to check DNS records
You might look up DNS records to verify an email configuration is correct (MX and TXT records for SPF, DKIM, DMARC), confirm that a new domain is pointing to the right server after a hosting change, check which nameservers are authoritative for a domain, troubleshoot why a website is unreachable, or investigate whether a domain is legitimate before clicking a link. DNS propagation after a change can take up to 48 hours — this tool shows the current live state from authoritative servers.
DNS and your privacy
By default, DNS queries are sent unencrypted to your ISP's resolver, meaning your ISP can see every domain you visit. Modern privacy-preserving alternatives include DNS over HTTPS (DoH) and DNS over TLS (DoT), which encrypt lookups so your ISP cannot read them. Switching to a privacy-respecting DNS resolver like Cloudflare's 1.1.1.1 or Google's 8.8.8.8 is one of the simplest steps you can take to improve your browsing privacy.
