An IPv6 address is composed of eight groups of four hexadecimal digits separated by colons, such as 2001:0db8:85a3:0000:0000:8a2e:0370:7334. An IPv4 address consists of four numbers separated by periods, each ranging from 0 to 255, such as 192.168.1.1. What is an IP AddressĪn IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. The network identifier specifies which network the device is attached to, while the host identifier identifies the specific device on that network. An IP address is composed of two parts: a network identifier and a host identifier. IP (Internet Protocol) addresses are logical identifiers used by routing protocols to identify devices on a network. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.
MAC addresses are used as network addresses for most IEEE 802 network technologies, including Ethernet and Wi-Fi. A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications on the physical network segment.
