What DNS Lookup helps you do

Query common DNS record types through Cloudflare's public DNS-over-HTTPS resolver and inspect status, TTL, and answer records from your browser. Useful for mail, web, and certificate troubleshooting — not a replacement for authoritative zone editing.

The hostname and record type are sent to Cloudflare's encrypted DNS-over-HTTPS resolver. Haivix does not store the query.

How it works

Haivix sends the hostname (and record type) to https://cloudflare-dns.com/dns-query with JSON accept headers. PTR queries reverse IPv4 dotted quads into in-addr.arpa form automatically.

How to use DNS Lookup

Enter a hostname or IPv4 address, choose A, AAAA, MX, TXT, or another supported record type, then run the lookup.
Read the response status (NOERROR, NXDOMAIN, etc.), TTL values, and answer records in the output panel.
Copy results into a ticket or compare with authoritative nameserver answers if propagation is in question.

When to use it

Checking whether a domain resolves before a site launch
Inspecting MX or TXT records for mail and verification workflows
Confirming CAA or CNAME chains during certificate troubleshooting

When not to use it

Editing DNS zones (this tool is read-only lookup)
Measuring global propagation across all resolvers worldwide
Diagnosing DNSSEC chain validation failures in depth

Example

Query TXT on your domain to see SPF/DKIM-related records returned by the public resolver — compare TTL and values with your DNS provider's editor.

What to know before you start

Queries go to Cloudflare's public DoH resolver — not your ISP or internal AD DNS.
Haivix does not store queries, but the resolver sees the hostname and record type.
Split-horizon or private zones may not be visible from the public internet.

Common mistakes

Assuming one resolver's answer proves authoritative zone correctness everywhere
Querying CNAME targets without following the full chain manually
Using cached TTL from an old answer after a recent DNS change
