About The DNS Zone Parser

DNS Zone Parser reads zone-file text and summarizes supported DNS records by type and value. It helps with quick review before migrations, audits, documentation, or troubleshooting.

The parser runs locally in your browser and does not query live DNS. It ignores directives such as $TTL, strips semicolon comments outside quotes, and extracts common record types from zone lines.

How to Parse a DNS Zone File Online

1. Paste zone-file text into Zone file input.
2. Click Parse Zone File.
3. Review total record count, record-type counts, and the first parsed records.
4. Use Load sample to test expected formatting.
5. Copy the output for migration notes or audit records.

Choosing Options Correctly

Zone text:
Use raw zone-file snippets with record names, optional class/TTL tokens, record types, and values. This parser is for text inspection, not authoritative DNS validation.

Common Use Cases

• Counting record types before a DNS migration.
• Checking whether important A, MX, NS, TXT, or CNAME records appear in a zone file.
• Preparing a concise summary for change review.
• Learning how common DNS records are represented in zone text.

Quick FAQ

Does this validate live DNS?
No. It parses zone-file text and does not query authoritative nameservers.

Why did a record not appear?
The line may use unsupported syntax, inherited owner names, multiline records, comments, or directives the parser does not handle.

Is my zone file uploaded?
No. Zone parsing is designed to run in the browser.

Can I use it before migration?
Yes for a quick review, but validate the final zone with authoritative DNS tooling before changing production DNS.
