What is an IP address? What role does it play? Describe its notation (decimal notation, number of bits, host part v network part)
An IP address is a unique identifier assigned to each device connected to a network. It serves 2 roles, identifying the host or network interface and providing the location of the host in the network which is essential for routing data to its destination.
IPv4 is 32 bits long in dotted decimal and is in 4 octets
IPv6 is 239 bits long in hexadecimal which has 8 groups of 4 hexadecimal digits.
IPv4 - 192.168.1.10 network part (192.168.1) host part (10) /24
IPv6- split 4 and 4 with the ending of /64
Differences- IPv4: 32 bits 4.2 billion addresses IPv6: 128 bits (very large amount)
What is the difference between IPv4 and IPv6? (Both in their roles, benefits and appearance)
IPv4 has been widely used since 1983 and has approx 4.3 billion addresses compared to ipv6 having 340 trillion trillion trillion.
IPv6 has better security, efficiency and support for modern networks. End-to-end encryption is a simpler format allowing for increased performance and efficiency.
