Internet Protocol version 4 (IPv4) was the first major version of IP. This is the dominant protocol of the Internet. However, iPv6 is active and in use, and its deployment is increasing all over the world. Addressing and routing are the most complex aspects of IP. IPv4 addresses are, most of the time, written in a way with 4 decimal numbers starting from 0 up to 255 and separated by a period. For example: 172.128.1.2 There is a minimum address and maximum address; the possible minimum address is 0.0.0.0 and the possible maximum address is 255.255.255.255. 地址. IPv4使用32位(4字节)地址,因此地址空间中只有4,294,967,296(2 32 )个地址。 不过,一些地址是为特殊用途所保留的,如专用网络(约1800万个地址)和多播地址(约2.7亿个地址),这减少了可在互联网上路由的地址数量。 An IPv4 address ("IP address") is 32 bits long and is written in dot-decimal notation (e.g., 127.0.0.1). Internally in lwIP, IP addresses are held in a structure called struct ip_addr, which just holds an unsigned 32-bit word. Therefore, to set an IP address, the following code can be used:#include struct ip_addr local; IP4_ADDR(&local,127,0,0,1);// Set local= "127.0.0.1 IPv4 je popsána IETF v RFC 791 (září 1981), které nahradilo RFC 760 (leden 1980) a je standardizována jako MIL-STD-1777 Ministerstvem obrany USA. IPv4 je datově orientovaný protokol, který je používán v sítích s přepojováním paketů (např. Ethernet).

An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. Functionality. IPv4 uses a 32-bit address scheme allowing a total of 2 to the power of 32 addresses or just over 4 billion addresses.This is based on the best-effort model. The model makes sure that there is the avoidance of duplicate delivery. All these aspects are handled by the upper layer of transport.This version of IP is used as the basis of the internet, and it establishes all the rules Internet Protocol version 4 (IPv4) was the first major version of IP.

IPv4 privát címtartomány. Azoknak a számítógépeknek, amelyek nincsenek direkt módon az internetre kapcsolva, például belső hálózatra kapcsolt vállalati gépek, nem szükséges globálisan egyedi IP-címmel rendelkezniük. Ezeknek a gépeknek három IPv4 címtartomány van fenntartva az RFC 1918 szerint. Ezek a címek nem

Internet Protocol version 4(インターネットプロトコルバージョン4)、IPv4(アイピーブイ4)は、Internet Protocolの一種で、OSI参照モデルにおいてネットワーク層に位置付けられるプロトコルである。. 転送の単位であるパケットの経路選択と、その断片化と再構築を主な機能とする。 A subnetwork or subnet is a logical subdivision of an IP network.: 1,16 The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP addresses.This results in the logical division of an IP address into two fields, the network number or routing prefix and the rest field IPv4 sử dụng 32 bits để đánh địa chỉ, theo đó, số địa chỉ tối đa có thể sử dụng là 4.294.967.296 (2 32).

Both the IPv4 and the IPv6 specifications define private IP address ranges. These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments.. Private network addresses are not allocated to any specific organization. Anyone may use these addresses without 地址. IPv4使用32位(4字节)地址,因此地址空间中只有4,294,967,296(2 32 )个地址。 不过,一些地址是为特殊用途所保留的,如专用网络(约1800万个地址)和多播地址(约2.7亿个地址),这减少了可在互联网上路由的地址数量。 随着地址不断被分配给最终用户,IPv4地址枯竭问题也在随之产生。 Internet Protocol version 4 (IPv4) je v informatice čtvrtá revize IP (Internet Protocol) a zároveň jeho první verze, která se masivně rozšířila. Spolu s IPv6 vytvářejí základ pro komunikaci v rámci sítě Internet.IPv4 je popsána IETF v RFC 791 (září 1981), které nahradilo RFC 760 (leden 1980) a je standardizována jako MIL-STD-1777 Ministerstvem obrany USA.
