IPv4 (Internet Protocol version 4) is the fourth version of the Internet Protocol, and is the most widely used version of the Internet Protocol today. It uses a 32–bit address space and supports a maximum of 4.3 billion addresses. IPv4 is a connectionless, best–effort delivery protocol which means packets are sent but not guaranteed to reach the recipient. IPv6 (Internet Protocol version 6) is the newest version of the Internet Protocol, and was designed to replace the current IPv4. It uses 128–bit addresses, resulting in much larger address space (2^128 or 340 trillion, trillion, trillion).
IPv6 also provides improved security, auto–configuration capabilities, and improved performance by allowing direct data flow between endpoints. Additionally, IPv6 also has built–in mobility features that allow for devices to change IP addresses or have multiple IP addresses.
