What is Internet Protocol Version 4 (IPv4)?

What does IPv4 stand for?

Internet Protocol Version 4 (IPv4) is the fourth revision of the Internet Protocol and a extensively used protocol in inFormation communique over extraordinary forms of Networks. IPv4 is a Connectionless Protocol utilized in Packet-Switched Layer networks, along with Ethernet. It presents the logical connection between commUnity gadgets by way of supplying identification for every tool. There are many approaches to configure IPv4 with all types of Devices – such as manual and automatic Configurations – relying on the network type.

IPv4 is based totally at the fine-attempt Model. This model ensures neither shipPing nor avoidance of replica shipping; these aspects are treated through the upper layer transport.

What Does Internet Protocol Version 4 Mean?

IPv4 is described and specified in IETF e-book RFC 791. It is used inside the packet-switched Hyperlink layer within the OSI model.

IPv4 Makes use of 32-Bit addresses for Ethernet conversation in 5 lessons: A, B, C, D and E. Classes A, B and C have a specific bit length for addressing the network Host. Class D addresses are reserved for Multicasting, while magNiFicence E addresses are reserved for destiny use.

Class A has Subnet Masks 255.Zero.0.0 or /8, B has subnet mask 255.255.Zero.0 or /16 and class C has subnet masks 255.255.255.Zero or /24. For Instance, with a /sixteen subnet masks, the commuNity 192.168.0.0 may additionally use the cope with Variety of 192.168.0.0 to 192.168.255.255. Network hosts can take any address from this Range; but, deal with 192.168.255.255 is reserved for broadCast within the community. The most variety of host addresses IPv4 can assign to quit users is 232.

IPv6 offers a standardized answer to conquer IPv4’s limiations. Because of its 128-Bit cope with period, it could define up to 2,128 addresses.
