Ø The world's population is currently over 7 billion, and it is anticipated to be 8 billion by 2025. Ø Currently 45% of the world's population are Internet users and this is set to rise. [ ~ 3.5 billion global internet users ]Ø Many users require multiple IP addresses to cater for personal devices each needing its own IP address.Ø IPv4 has ~4.2 billion possible IP addresses. [ 32 bits ]Ø IPv6 ~ over 340 trillion trillion trillion addresses. [ 128 bits ]

Converting Binary to Hexadecimal00100000000000010000110110111000101011000001000011111110000000010000000000000000000000000000000000000000000000000000000000000000
Step 1 – Break the Binary into 8 blocks of 16 bits ( 8 x 16 bit = 128 bits )0010000000000001 0000110110111000 1010110000010000 1111111000000001
