It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. This address is a 32-bit address represented within the system in binary form: 10010001.00001010.00100010.00000011. The 32 bits are split into 4 bytes and each byte is separated by a dot(.).

The method divides the IP address space for Internet Protocol version 4 into five address classes based on the leading four address bits. IPv4 uses a 32-bit address space wh IP address classes. Class D is for multicast networking and the class E address range is reserved for future or experimental purposes. The size of IPv6's address space — 340 duodecillion — is much, much larger than IPv4. All the five classes are identified by the first octet of IP Address. An IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network.Addresses in IPv4 are 32-bits long. IPv4 uses 32 bits for addressing. Classes A, B, and C provide unicast addresses for networks of three different network sizes. A typical IP address appears like this:192.168.0.1 For example, 145.10.34.3. IPv4 was the first version deployed for production in the ARPANET in 1983. MAC address (Hardware address) is a globally unique address which represents the network card and cannot be changed.

It still routes most Internet traffic today, despite the ongoing deployment of a successor protocol, IPv6. IPv4 addresses 32 bit binary addresses (divided into 4 octets) used by the Internet Protocol (OSI Layer 3) for delivering packet to a device located in same or remote network.

Internet Protocol version 4 is the fourth version of the Internet Protocol. IPv4 is described in IETF publication RFC 791, replacing an earlier definition. Broadly, the IPv4 Addressing system is divided into five classes of IP Addresses. S A classful network is a network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing in 1993. This allows for a maximum of 4,294,967,296 (2 32) unique addresses.Addresses in IPv6 are 128-bits, which allows for 3.4 x 10 38 (2 128) unique addresses.. What is the IPv4 Address?
IPv4 address class: An IPv4 address class is a categorical division of internet protocol addresses in IPv4-based routing. With an IPv4 IP address, there are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B, and C are commonly used. An IP address uniquely identifies each host and router.
One of the usual IP addresses that we see. So it is of this form:a.b.c.dWhere the value of a,b,c or d is between 0-255 decimal. This IP address is 32 bits long. Internet Protocol hierarchy contains several classes of IP Addresses to be used efficiently in various situations as per the requirement of hosts per network.
