Frequently Asked Questions
What is an OUI in a MAC address?
An Organizationally Unique Identifier (OUI) is the first 3 octets (24 bits) of a MAC address that identifies the device manufacturer (e.g. Cisco, Apple, Intel).
What are the common MAC address delimiter formats?
Standard IEEE formats use colons (00:1A:2B:3C:4D:5E), Windows uses hyphens (00-1A-2B-3C-4D-5E), and Cisco switches use dotted quads (001a.2b3c.4d5e).
