IPv4 Versus IPv6 – Explained
IPv4 is the acronym stands for internet protocol version 4. This is the fourth edition of internet protocol that is designed to identify the devices on the network through an addressing system. This version is made for use in interconnected systems of packet switched communication network.
To explain the IPv4 vs. IPv6 is important to compare the differences between the two. In the IPv4 addresses are 32 bits which means they are 4 bytes long. In this version using the address (A) resource records in DNS to map host names to IPv4 addresses. It also uses a pointer (PTR) in the IN-ADDR.ARPA DNS domain to map IPv4 addresses to host names. Internet protocol version also makes an optional IPSec and supported externally. Header in IPv4 is not an identifier of packet flow for QoS handling by routers. The router and the host sends a packet fragment can be in the internet protocol version.
On the other hand is very different IPv6. This version provides a special packet format to reduce the packet header processing by the router. IPv4 packet header and the difference of two IPv6 protocol makes interoperability impossible. Other specifications that make the preferred IPv6 is its ability to transmit a single packet to more than one goal in a single send operation. Host IPv6 stateless auto-configuration of addresses that allow them to configure itself automatically when connected to an IPv6 network through a directed version of the Internet message control protocol.
