Why does my new record not show up?

DNS changes take time to propagate based on the old record's TTL. Try the Google or Cloudflare resolver — they often pick up changes faster than ISP resolvers.

Why is the TTL shown as 0 or missing?

TTL is only available for A and AAAA records via the Node DNS API. Other types are returned without TTL information.

What's the difference between A and CNAME?

An A record points a name directly at an IP. A CNAME points one name at another name (which then resolves to an A record). You can't have both A and CNAME on the same name at the apex.

Why no PTR (reverse DNS)?

PTR records are queried by IP, not by domain. The IP Info tool does reverse DNS as part of its lookup.

About DNS Lookup

DNS Lookup queries the DNS system for a domain and returns every common record type at once: A (IPv4), AAAA (IPv6), CNAME (alias), MX (mail exchanger), TXT (verification, SPF, DKIM), NS (authoritative name servers), SOA (zone authority), and CAA (certificate issuance policy). Each record is shown with its TTL where the resolver provides one. You can switch the resolver between your hosting provider's default, Google Public DNS (8.8.8.8), and Cloudflare DNS (1.1.1.1). Different resolvers cache differently, so if you just changed a record and want to see whether the world has caught up, switching is faster than running 'dig' against each one. Browsers cannot resolve DNS directly — they delegate to the operating system, which delegates to a resolver. This tool queries DNS from a Node.js server, which means it returns the records authoritatively rather than whatever your browser's HTTP cache happens to have remembered. Common use cases: verifying a DNS change has propagated; debugging email delivery by reading SPF/DKIM/DMARC TXT records; finding the CDN behind a CNAME; auditing CAA records before issuing a new certificate; counting MX records to spot a misconfigured mail setup.

How DNS Lookup works

Enter a domain (no protocol, no path).
Optionally pick a public resolver (Google or Cloudflare) instead of the system default.
All eight record types are queried in parallel.
Records are returned grouped by type. Empty types show 'no records' rather than an error.
MX records are sorted by priority. NS records are normalized to lowercase.

When to use DNS Lookup

Confirm DNS propagation after pointing a domain at a new IP.
Read SPF, DKIM, DMARC TXT records to debug email deliverability.
Find the CDN or hosting provider behind a CNAME chain.
Audit CAA records before requesting a new TLS certificate.
Verify nameserver delegation matches the registrar.
Spot misconfigured mail setups (no MX, multiple priorities at the same level).
