Frequently Asked Questions
- Which MAC address formats are recognised?
- Six pairs of hex digits separated by colons or hyphens — AA:BB:CC:DD:EE:FF and AA-BB-CC-DD-EE-FF both match, upper or lower case. Cisco dotted format (aabb.ccdd.eeff) is not matched.
- Where would I extract MAC addresses from?
- DHCP server logs, ARP table dumps, switch configuration exports, and network inventory documents — paste the raw text and get a clean list for asset tracking or filtering rules.
- I have a MAC address — can I find out who made the device?
- Yes, but that's a different lookup than this page does. Use the MAC Address Vendor Lookup — paste a single address and it identifies the manufacturer from its OUI prefix.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
