Redact MAC addresses from text, JSON, and CSV

A MAC address identifies a network interface and, through it, usually a person: it appears in router logs, captive portals, and asset registers.

Try it on the live API No signup. 2,000 characters, 20 runs per 10 minutes.

How Redactly detects MAC addresses

  • Matched by regex for six hex pairs separated by colons or hyphens.
  • Case-insensitive, because captures differ between vendors.
  • Runs independently of the model.

Why redact MAC addresses?

Network logs are among the most frequently shared files in incident response, and they carry MAC addresses throughout.

Example request

curl -X POST https://api.bitbanger.in/v1/redact \
  -H "X-API-Key: rdct_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"text": "DHCP lease 00:1A:2B:3C:4D:5E assigned to desk-14.", "style": "replace"}'

Every hit in the response carries entity, text, start, and end. The offsets index into the text you sent, so you can apply the redactions to your own copy of the document. The full response schema is in the API reference.

Questions

Does Redactly redact MAC addresses automatically?

Yes. Send text to the API and every detected type is redacted, including MAC addresses. To redact only this type, pass the value device.mac_address in the entities filter. No training or configuration is required.

What happens to MAC addresses after redaction?

With style set to replace, each match becomes [device.mac_address] — the entity type in square brackets. Setting style to mask replaces every character with a block character, and remove deletes the span entirely.
