About DNS Lookup
Look up public A, AAAA, CNAME, MX and TXT DNS records for a hostname. PHP queries public DNS for common record types including A, AAAA, CNAME, MX and TXT.
How to use DNS Lookup
Enter a hostname and run the lookup. ToolFlow requests common public A, AAAA, CNAME, MX and TXT records and returns the records that DNS publishes.
When DNS Lookup is useful
- Investigate a public website during development, deployment or SEO review.
- Verify an HTTP, DNS or TLS detail before changing server configuration.
- Capture a point-in-time diagnostic result without installing a local command-line tool.
Practical tips
- Run diagnostics against a public URL you are authorized to test.
- A single request is a point-in-time measurement; network and server conditions can change between checks.
- For production decisions, confirm important findings with server logs or authoritative configuration data.
DNS Lookup FAQ
Does DNS Lookup change my original input?
No. ToolFlow works on a temporary upload or submitted value and returns a separate result. Your local original is not overwritten.
Do I need to install software to use DNS Lookup?
No browser extension or desktop application is required. Some file tools depend on server modules such as FFmpeg, GD, Poppler or LibreOffice being enabled by the site operator.
