Main difference ipv4 vs ipv6 speed
What is IPv4? ipv4 vs ipv6 speed
IPv4 or Internet Protocol version 4 is the fourth version of the Internet Protocol (IP) and routes the most traffic on the Internet today. It is the predecessor of IPv6. IPv4 is a connectionless protocol for use in packet-switched networks. IPv4 uses a 32-bit numerical address scheme that allows a total of 2 3 that came to 4,294,967,296. As addresses were assigned to users and the number of addresses that remained unassigned decreased. IPV4 was implemented in 1981 and the prefix notation is 18.104.22.168-24. It was designed around that time when the modern multi-device world wasn’t even unfathomable.
What is IPv6?
IPv6 or Internet Protocol Version 6 is the latest version of the Internet Protocol and routes a greater amount of traffic on the Internet today compared to IPv4. It was developed by the Internet Engineering Task Force (IETF) in 1999. It was designed and released with the goal of replacing IPv4. The Internet protocol is the main provider and system for identifying and locating computers on networks. IPv6 uses a 128-bit numerical address scheme that allows a total of 2 128 that made up 340, trillion, trillion, trillion Internet addresses. It allows every person on earth who uses the internet to have billions of addresses for every device they own.
- IPv4 allows 4 billion Internet addresses, while IPv6 allows 340, trillion, trillion, trillion Internet addresses.
- The size of the IPv4 address is a 32-bit number, while the size of the IPv6 address is a 128-bit number.
- IPv4 was released in 1981, while IPv6 was released in 1999.
- The address format of IPv4 is 22.214.171.124 which is dotted decimal notation, while IPv6 uses hexadecimal notation which is 3FFE: F200: 0234: AB00: 0123: 4567: 8901: ABCD.
- The IPv4 prefix notation is 126.96.36.199/24 while the IPv6 prefix notation is 3FFE: F200: 0234 :: / 48.
- Security, which was always a challenge in IPv4, is an integral part of IPv6 which is Integrated Network Layer Security (IPsec).
- The structure of the IPv6 header is more improved and with less processing head. Many of the fields in the IPV4 header were optional and infrequently used.
- IPv6 has more efficient routing. IPv6 routers no longer have to fragment packets, an overhead intensive process that simply slows down a network. ipv4 vs ipv6 speed
