DNS Lookup

Query DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA) for any domain using Google DNS-over-HTTPS.

DNS Lookup — DNS is the internet's phone book — it turns the domain you type into the IP address a server actually lives at. This tool queries DNS records for any domain using Google's free DNS-over-HTTPS endpoint, so you can see exactly which servers a domain points to without touching the command line.

This tool queries Google DNS-over-HTTPS. The domain you query is not user-private data, and Uttir never sees or logs the result.

What is dns lookup?

DNS is the internet's phone book — it turns the domain you type into the IP address a server actually lives at. This tool queries DNS records for any domain using Google's free DNS-over-HTTPS endpoint, so you can see exactly which servers a domain points to without touching the command line.

Useful when you have just changed nameservers and want to confirm they have propagated, when debugging email delivery (MX), when verifying domain ownership for a certificate (TXT / CAA), or when investigating a domain you are about to trust.

How to use it

  1. Enter a domain

    e.g. github.com — no protocol, no path.

  2. Pick a record type

    A is the default (IPv4 addresses).

  3. Read the results

    Each answer shows the data and a TTL in seconds.

Examples

Find the IPs for a domain

Default A record lookup for github.com.

github.com / A

Result: Multiple A records with TTLs. Each is an IPv4 address that the domain resolves to.

Check who handles email

MX records tell you which servers receive email for the domain.

github.com / MX

Result: A list of mail exchange records, with priority numbers — lower = preferred.
