DNS Lookup

Query the DNS records behind any hostname and see exactly how it is configured. This tool returns A, AAAA, MX, NS, TXT, CNAME and CAA records so you can verify where a domain points, how its email is routed and what policies are set.

What the DNS lookup does

DNS is the address book of the internet, and this tool reads that address book for any hostname you enter. It fetches the records that control how a domain behaves: A and AAAA map the name to IPv4 and IPv6 addresses, MX defines where email is delivered, NS lists the authoritative name servers, TXT holds verification and policy strings like SPF and DKIM, CNAME shows aliases that point one name at another, and CAA declares which certificate authorities may issue SSL certificates for the domain.

How to use it

  • Enter a hostname such as example.com or mail.example.com.
  • Review the A and AAAA records to confirm the server addresses.
  • Check MX records when you are diagnosing email delivery.
  • Read TXT records to verify SPF, DKIM and domain ownership entries.
  • Inspect NS and CAA records when migrating hosts or issuing certificates.

Results come from a live DNS query, so you see the records as they currently resolve.

Why it matters

Almost every website and email problem traces back to DNS at some point. A missing or wrong A record means a site will not load. Broken MX or SPF records send email straight to spam or nowhere at all. When you move hosting, comparing old and new records is how you confirm the switch actually happened. Developers and site owners lean on DNS lookups to verify changes have propagated and to catch typos before they cause outages. At Digzy Technology, our studio in Bali, Indonesia, we check DNS on every launch and migration so a site and its email come online cleanly. Whether you are setting up a new domain, troubleshooting delivery, or auditing security policies, seeing the full record set in one place makes the whole picture obvious.

FAQ

Frequently asked questions

Why do my new DNS changes not show up yet?
DNS changes take time to propagate as caches expire around the world, governed by each record's TTL. It can take from minutes to a day, so re-check periodically after making edits.
What is the difference between an A record and a CNAME?
An A record points a name directly to an IP address, while a CNAME points one name at another name as an alias. You cannot use a CNAME at the root of a domain.
How do I check my email configuration?
Look at your MX records to see where mail is routed, then check TXT records for SPF and DKIM entries, which control deliverability and authentication.
What is a CAA record for?
A CAA record lists which certificate authorities are allowed to issue SSL certificates for your domain, adding a layer of protection against unauthorized certificates.
