What is an IP address

An Internet Protocol (IP) address is an unique set of numbers assigned to PCs or servers that host websites, printers, smartphones, tablets and any other computing device that is connected to the internet.

The current IP address scheme, version 4 or IPv4 was started in 1981; and is due to be exhausted soon.  The next-generation of IP address, IPv6 is a 128-bit number, which allows for 340 undecillion (340 followed by 36 zeros) different addresses.

If 3.4 billion addresses (IPv4, based on 32-bit number) were the size of a golf ball, then 340 undecillion addresses would be the size of the sun.

IPv4 address is denoted as a dotted decimal number, which ranges from 0.0.0.0 to 255.255.255.255.   IPv6 address uses a hexadecimal notation such as 2001:0db8:85a3:0000:8a2e:0370:7334, comprising 39 digits, letters and semi-colons.
