INTRODUCTION The original intention was to assign a unique IP address to each computer that is connected to the Internet. But after the private networks developed and the address space needed to be conserved, this was found not to be always necessary. Today, Private Networks typically connect to the Internet using the Network Address Translation. Technologies such as “any cast” also allow multiple computers to use the same IP address but at different portions of the Internet, so that private networks can handle more consumers.
IPV4 and IPV6 There are two types of IP addresses: IPv4 and IPv6. An IPv4 address, for example, 59.93.88.169, has 4 octets separated by decimals. They are called octets because each of them represents 8 bits (in binary) of the address. The first octet represents the network address and the last three octets are to identify the host. Each of the octets can take any number from 0 to 255 as that is the largest number possible in an 8-bit binary. This limits the number of unique possible combinations of IPv4 addresses to 232. IPv6 on the other hand uses hexadecimal system and each address is assigned a space of 16 bytes (compared to 4 bytes in IPv4). A typical IPv6 address looks like this: 2001:0db8:85a3:08d3:1319:8a2e:0370:7334.
