Definition - What does Internet Protocol Version 4 (IPv4) mean?

Internet Protocol Version 4 (IPv4) is the fourth revision of the IP and a widely used protocol in data communication over different kinds of networks. IPv4 is a connectionless protocol used in packet-switched layer networks, such as Ethernet. It provides the logical connection between network devices by providing identification for each device. There are many ways to configure IPv4 with all kinds of devices - including manual and automatic configurations - depending on the network type.

IPv4 is based on the best-effort model. This model guarantees neither delivery nor avoidance of duplicate delivery; these aspects are handled by the upper layer transport.

Ethernet is a physical and data link layer technology for local area networks (LANs). Ethernet was invented by engineer Robert Metacafe.

When first widely deployed in the 1980s, Ethernet supported a maximum theoretical data rate of 10 megabits per second (Mbps).

Later, so-called "Fast Ethernet" standards increased this maximum data rate to 100 Mbps. Gigabit Ethernet technology further extends peak performance up to 1000 Mbps, and 10 Gigabit Ethernet technology also exists.

IPv6 is a 128 bits because its divided into 8 block and each block consists 16 bit because it is in hexadecimal so its 128 bits long.

For an example:

Suppose we have an ipv6 ABCD:12CD:00AC:BC23:0000:0000:1234:0000.

So ABCD is in hexadecimal. We will be convert in binary form.

After converting it will be 1010101111001101.

@ALL.

We are using bsnl network using Dlink router its connected switch. Switch to patch panel. When I connected switch port to system or laptop its internet working fine. Next, when I connect the to from switch to patch panel internet will go very slow it's working very slow down what is the issue please let me know?

IPv4 & IPv6 are both IP addresses that are binary numbers. IPv4 is a 32-bit binary number, and IPv6 is a 128-bit binary number address. IPv4 addresses are separated by periods, while IPv6 addresses are separated by colons. Both IP addresses are used to identify machines connected to a network.

IPv6 is the successor to the Internet's first addressing infrastructure, Internet Protocol version 4 (IPv4). In contrast to IPv4, which defined an IP address as a 32-bit value, IPv6 addresses have a size of 128 bits. Therefore, IPv6 has a vastly enlarged address space compared to IPv4.

IPv4 - 32 bit-- represent in Octet form.
Example -- 69.89.31.226 -> 01000101.01011001.00011111.11100010->
4 octets -> 4x8 ->32 bit.

IPv6 - 128 bit(hexa decimal format).
Example -- 2002:4559:1FE2:0000:0000:0000:4559:1FE2 -> 8 x 16 -> 128 bit.

Hope this helps.

We are using both IP version 6. and IP version 4 . IP version 6 is Simple Internet Protocol and IP version 4 is Internet Protocol base on TCP/IP which means transmission control protocol over internet, Thanks @Prabhu.

IPv6 addresses are 128 bits in length and are made up of hexadecimal characters. In IPv4, each octet consists of a decimal number ranging from 0 to 255.

These numbers are typically separated by periods.

IPV4 is the 32bit and IPV6 is the 128bit its taken long size and it's infrastructure is didn't made in India so we are not using IPV6.

As compared to IPV4 it is the most faster.
