Does this tool query my domain's DNS?

No. It only parses and explains text you paste. No DNS lookup is performed, so the domain name you enter is never sent to any server — it stays in your browser.

What are the fields in a zone-file line?

A standard line is: name, optional TTL, optional class (almost always IN), type, then the record data. For example 'example.com. 3600 IN MX 10 mail.example.com.' has name example.com., TTL 3600, class IN, type MX, and data '10 mail.example.com.'.

How accurate is the parsing?

The parser follows the standard zone-file field order (name, optional TTL, optional class, type, then record data) and detects the type from the known record-type set. Unusual multi-line or parenthesised records may only be partially parsed.

What does the priority number in an MX record mean?

In an MX record like '10 mail.example.com.', the 10 is the priority — a lower number is preferred. Mail is delivered to the lowest-priority server first, with higher numbers acting as backups.

Why does it not show the live value of my record?

Browsers cannot resolve arbitrary DNS record types, and resolving would leak the queried name. This privacy-first tool is a reference and parser, so paste the record from your DNS provider to have it explained.

Which record types does it explain?

The common ones: A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV and CAA. Each comes with a plain-English summary and a realistic zone-file example you can adapt.

DNS Record Explainer

DNS record explainer

Understand DNS without leaking anything. Paste a single zone-file line and the tool labels its name, TTL, class, type and record data, then explains what that record type does. It is for anyone editing DNS at a registrar or host who wants to confirm a record is shaped correctly.

How it works

A standard zone-file line follows the order name [TTL] [class] type rdata, where the class is almost always IN and may be omitted. The parser tokenises the line on whitespace, finds the type token by matching it against the known record-type set, and labels every field around it — the name comes first, a numeric token before the type is the TTL, and everything after the type is the record data. It then shows a plain-English summary of that record type. No network query is made, so nothing about your domain leaves the browser.

Example

Paste:

example.com.  3600  IN  MX  10 mail.example.com.

Field	Value
Name	example.com.
TTL	3600
Class	IN
Type	MX (mail exchange)
Data	10 mail.example.com.

The summary explains that an MX record names the mail server and its priority (10 here, where lower is preferred). It covers A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV and CAA, each with an example you can copy. No DNS query is ever made — this is a reference and parser that runs entirely in your browser, so the domain you paste is never sent anywhere.
