Tentang alat ini

DNS records control how a domain name resolves - which server it points to, how email is routed, and more. This tool queries all the common DNS record types (A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV, CAA) for any domain, useful for debugging domain configuration, verifying DNS changes have propagated, or investigating how a domain is set up.

Cara menggunakan alat ini

  1. Enter domain nameQuery target hostname you want to diagnose or verify.
  2. Select record typesCheck A/AAAA/CNAME/MX/TXT/NS and other records as needed.
  3. Review DNS responsesInspect values, priorities, TTL, and delegation consistency.
  4. Validate propagation/configCompare expected setup with returned records and fix mismatches.

Mengapa menggunakannya

  • Speeds up troubleshooting for domain and email routing issues.
  • Provides one place to inspect major DNS record families.
  • Helpful for propagation checks after DNS changes.
  • Useful for security and deliverability verification workflows.

Penggunaan umum

  • Debugging website pointing to wrong server IP.
  • Verifying MX/TXT records for email provider setup.
  • Checking SPF/DKIM/DMARC text records quickly.
  • Auditing nameserver and CAA policies for domain control.

Tips untuk hasil lebih baik

  • Check TTL before expecting immediate global propagation.
  • Validate both apex and subdomain records separately.
  • Use TXT lookups to confirm SPF and verification tokens.
  • Document final DNS values to prevent accidental future drift.

Kesalahan yang harus dihindari

  • Assuming local resolver cache reflects global propagation state.
  • Editing wrong DNS zone while expecting immediate fix.
  • Forgetting AAAA record when IPv6 traffic matters.
  • Overlooking MX priority order during mail migration.

Pertanyaan yang sering diajukan

A records point a domain to an IPv4 address. AAAA records point to an IPv6 address - modern domains often have both to support visitors on either type of network.

They specify which mail servers handle email for a domain, and in what priority order - essential for verifying email is routed to the correct provider (like Google Workspace or a custom mail server).

DNS changes take time to propagate globally due to caching (TTL - time to live) at various points across the internet - it can take anywhere from minutes to 24-48 hours depending on the record's TTL setting and caching along the way.

Yes. Dns Lookup is free for normal use with no account required, and ToolBox does not add a watermark to your result.

Most tools in this category run in your browser so the file stays on your device. If a tool needs a temporary server job, files are handled for that job only and are not kept as a lasting archive.

No install needed. Open Dns Lookup in your browser, add your file or paste your input, then download or copy the result.

Yes on modern mobile browsers. For large files, a desktop browser is usually faster and more reliable.

Try a different quality or format setting, use a smaller input, or open a related tool (for example compress before convert). Keep a copy of the original file before replacing it.
