DNS Lookup

DNS is the phonebook of the internet, mapping domain names to the servers that actually handle them. This tool queries a domain's DNS records directly — A and AAAA for IP addresses, MX for mail routing, TXT for verification and SPF/DKIM records, CNAME for aliases, and NS for the authoritative nameservers — and returns them in a clean, readable list. Essential for verifying a domain migration, debugging email deliverability, or confirming a DNS change has propagated.

Domain Name

Queries all DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA, PTR, SRV) for the specified host.

Inspect Global Domain Records and Name Routing

DNS functions as the directory of the internet, translating human-readable domain names into the numeric IP addresses and routing instructions needed to direct web traffic. Whenever you migrate a site, set up custom email, or point a domain to a new host, DNS records control how those requests are directed.

The DNS Lookup tool queries authoritative nameservers directly, retrieving a clean, structured breakdown of a domain's public DNS configuration in real time.

Key Features

  • Multi-Record Parsing: Query and display key DNS record types in a single search:
  • A & AAAA Records: Map domain names to IPv4 and IPv6 server addresses.
  • MX Records: Identify mail server destinations and priority rankings for email handling.
  • TXT Records: Inspect domain ownership verifications, SPF (Sender Policy Framework), and DKIM security signatures.
  • CNAME Records: Track domain aliases and canonical mappings.
  • NS & SOA Records: Identify authoritative nameservers and zone administrative metadata.
  • Propagation Verification: Quickly verify whether recent DNS record additions or modifications have taken effect globally.
  • Deliverability Debugging: Inspect email routing rules and authentication records to troubleshoot delivery failures or spam flags.
  • Raw & Formatted Output: View organized data tables or inspect raw DNS response records for advanced network troubleshooting.

Common Use Cases

  • Domain & Host Migrations: Verify that A records correctly point to your new web server or load balancer IP address before shutting down old infrastructure.
  • Email Setup & Authentication: Confirm MX records point to your mail provider and validate TXT entries for SPF, DKIM, and DMARC to secure outgoing messages.
  • Third-Party Service Integration: Check TXT or CNAME records required to verify site ownership for webmaster tools, SSL provisioning, or CDN platforms.
