What type of address is 00-A1-C3-52-CE-11?

IP addresses use dotted-decimal notation for IPv4 (e.g., 192.168.1.1) or colon-separated hex groups for IPv6, not the six-octet hyphenated hex format shown.

A MAC (Media Access Control) address is a 48-bit hardware identifier written as six hexadecimal octets separated by hyphens or colons. The format XX-XX-XX-XX-XX-XX uniquely identifies a network interface at the data link layer. The value 00-A1-C3-52-CE-11 matches this exact structure, confirming it is a MAC address.

Host describes a device role on a network, not a distinct address format or type.

A broadcast MAC address is always FF-FF-FF-FF-FF-FF; the address shown does not match that reserved pattern.

Unicast describes a one-to-one transmission method rather than an address format type; the question asks what kind of address this is, which is MAC.
