DNS Lookup

Query live DNS-over-HTTPS records for A, AAAA, and MX responses. The check runs directly from your browser and does not use a Plain Tools proxy.

How it works

Enter a domain and this tool queries DNS-over-HTTPS endpoints directly from your browser. Results show current DNS answers, TTL values, and record data without file uploads or tracking scripts.

What these records mean

A Record

Maps the hostname to one or more IPv4 addresses.

AAAA Record

Maps the hostname to one or more IPv6 addresses.

MX Record

Specifies which mail servers accept email for the domain.

NS Record

Lists the authoritative nameservers for the DNS zone.

TXT Record

Publishes arbitrary text data such as SPF, DKIM, and verification tokens.

SOA Record

Defines the primary zone authority and refresh timing values.

CNAME Record

Aliases the hostname to another canonical hostname.

Why DNS matters

DNS is often the first layer to inspect when a website fails to load, email stops routing, or a domain verification token is rejected. A clean application stack can still look broken if the domain points to the wrong address, the wrong nameserver, or an outdated cached answer.

The main tool page is designed for active lookup workflows. It lets you query a hostname immediately, then move into a dedicated domain page if you want a fuller explanation, all major record types together, and shareable diagnostics for the same domain.
