Random DNS Record Fixture Generator

 
Documentation-safe DNS record generated locally in your browser with the Web Crypto API. No DNS lookups or network validation are performed.

Safe DNS fixtures

Generate one A, AAAA, CNAME, MX, or TXT record line using reserved example.com, example.net, and example.org hostnames plus RFC documentation IP ranges. Use these records for docs, mock API payloads, seed data, tests, and infrastructure UI examples without pointing at real customer infrastructure.

How it works

  1. Your browser draws random values from the Web Crypto API
  2. A common DNS record type is selected
  3. Hostnames stay under reserved example domains
  4. A and AAAA values use documentation-safe IP ranges
