IP ADRESS
IP address is a sequence of numbers that uniquely identifies the location of each computer or device connected to the Internet or any other network.
IPV4
STRUCTURE :
i. The network ID/part (first three numbers) identifies the network.
ii. The host ID/part (last number) identifies the specific computer.
Example:1.2.3.4 , 10.10.100.99 , 255.255.255.255
• IPv4 uses a 32-bit address
• Made up of four groups of decimal numbers,
• The number in each group is between 0 and 255,
• Separator: period(.)
• Each group consists of 8 bits, so 4 groups=32bits.
• The lowest IP address : 0.0.0.0 and the highest IP address : 255.255.255.255
IPV6
The growth of the Internet has led to a shortage of IPv4 addresses. Because of this increase, IPv4 addresses are running out
STRUCTURE :
• Each IPv6 address is represented as eight groups/fields of four *hexadecimal digits, separated by colons (:).
• Each group consists of 16 bits.
• Number in each group is between 0000 to FFFF
• Hence, total bits are 8 x 16 = 128 bits
• Total IPv6 addresses is 2 128
THE IMPORTANCE :
• Larger IP address space that provide enough address space for many decades to come.
• improved traffic routing
• Better security
• Better support for real time
• Includes Plug and play
• Better optimization
