Networked Equipment Addressing
IPv6 address
IPv6 address notation represents the 128 bits as 32 hexadecimal values
The hexadecimal 32 is in turn divided into 8 fields of 4 hexadecimal values divided by colons
Each
field of four hexadecimal values is called a block.
The IPv6 address has a three-part hierarchy:
● The global prefix, also called a site prefix, is the first three blocks of the address and is
assigned to an organization by an Internet names registry.
●The subnet ID includes the fourth block of the address
● The interface ID includes the last four blocks of the address. The network administrator
controls both the subnet and interface ID.
An IPv6 address can be abbreviated with the following rules:
● Omit leading zeroes in a 16-bit value.
● Replace one group of consecutive zeroes by a double colon.
You can assign the following IP address configuration information to a host:
● IP address - identifies the computer on the network
● Subnet mask - is used to identify the network on which the computer is connected
● Default gateway - identifies the device that the computer uses to access the Internet or another
network
● Optional values - such as the preferred Domain Name System (DNS) server address and the
alternate DNS server address
A Dynamic Host Configuration Protocol (DHCP) server automatically assigns IP addresses, which simplifies the addressing process
The DHCP server maintains a list of IP addresses to assign and manages the process so that every
device on the network receives a unique IP address
Before a computer on the network can take advantage of the DHCP services, the computer must be able to identify the server on the local network
