IPv4 & IPv6 are both IP addresses that are binary numbers. IPv4 is 32-bit binary number while IPv6 is 128-bit binary number address.
IPv4 address are separated by periods while IPv6 address are separated by colons.
Both are used to identify machines connected to a network. In principle, they are the same, but they are different in how they work.
Enrich Your Learning:
- An Internet Protocol address is also known as IP address.
- It is a numerical label which assigned to each device connected to a computer network which uses the IP for communication.
- IP address act as an identifier for a specific machine on a particular network.
- The IP address is also called IP number and internet address. IP address specifies the technical format of the addressing and packets scheme.
- Most networks combine IP with a TCP (Transmission Control Protocol). It also allows developing a virtual connection between a destination and a source.
What is IPv4?
- IPv4 was the first version of IP. It was deployed for production in the ARPANET in 1983.
- Today it is most widely used IP version. It is used to identify devices on a network using an addressing system.
- The IPv4 uses a 32-bit address scheme allowing to store 2^32 addresses which is more than 4 billion addresses.
- Till date, it is considered the primary Internet Protocol and carries 94% of Internet traffic.
What is IPv6?
- It is the most recent version of the Internet Protocol. Internet Engineer Taskforce initiated it in early 1994.
- The design and development of that suite is now called IPv6.
- This new IP address version is being deployed to fulfil the need for more Internet addresses. It was aimed to resolve issues which are associated with IPv4.
- With 128-bit address space, it allows 340 undecillion unique address space.
- IPv6 also called IPng (Internet Protocol next generation).
