A URL will allow you to access a specific file or resource that has been hosted on a server.

The MAC address is made up of six bytes of data, which is hexadecimal and divided into six bytes by colons. IP addresses are unique identifier for devices on an IP network. IP Addresses (IPv4), IPv6 addresses, and MAC Addresses are used to identify hardware devices. After this is completed, a 16-bit 0xFFFE is inserted between these two 24-bits to establish a 64-bit EUI address. A MAC address is made up of two 24-bit bits: one for an organization’s unique identifier (OUI) and the other for a network address controller (NIC). Is Mac Address An Ipv6 Address?Ĥ8-bit MAC addresses serve as the format address for IPv6 EUI-64. In some cases, interfaces’ identifier can be derived directly from their link- layer addresses. It is critical to remember that the link is unique. In contrast, the MAC address and the interface ID both have 48 bits.Īn interface identifier used in an IPv6 unicast address identifies a link’s interface. Navigate to TCP/IP and select it at the top of the menu.Īn IPv6 device will generate a 64- bit interface ID based on the MAC address of its interface. To change your preferences on your Mac, go to the Apple menu > System Preferences> Network, then select the Network service on the left, and then click on it to change your preferences. To configure IPv4 or IPv6 connections or to renew a DHCP lease, use the TCP/IP pane of your Mac’s Network preferences. This ensures that the IID is locally unique on a LAN. The low-order 24 bits of the IID are typically derived from the MAC address, with the high-order 8 bits set to the inverse of the Universal/Local (U/L) bit in the MAC address. The MAC address is divided into two 24-bit parts, and each part is mapped to a 16-bit field in the IID. The IID is generated from the interface’s MAC address, which is a 48-bit identifier assigned by the manufacturer. An IPv6 address is divided into two logical parts: the network prefix, which identifies the network, and the interface identifier (IID), which identifies a particular interface on that network. IPv6 addresses are 128-bit identifiers for interfaces and hosts.
