O IPv4 está descrito no IETF publicação RFC 791 (setembro de 1981), em substituição a anterior definição (RFC 760, de janeiro de 1980). O IPv4 é um protocolo sem conexão, para utilização de comutação de pacotes redes. Ele opera em um modelo de entrega por menor esforço, em que não garante a entrega, nem garante a sequência IPv4 לא מוודא את אמינות הנתונים, אלא רק את אמינות הפתיח. 32 הסיביות הבאות מכילות את כתובת ה-IP של השולח. 32 הסיביות הבאות מכילות את כתובת ה-IP של הנמען. IPv4, versiunea folosită până în 2011 pe scară largă, nu mai poate scala, numărul de stații conectate la o astfel de rețea fiind limitat la 4,3 miliarde.Ultimele adrese IPv4 au fost alocate de IANA la începutul anului 2011. IPv4 adrese. IPv4 adresa je u osnovi 32-bitni binarni broj.Kako je u pravilu vrlo teško pamtiti niz od 32 znaka '0' ili '1', češće se koriste druge notacije, a najčešće od svih decimalna notacija. IPv4 benytter 32-bit adresser, hvilket begrænser den til 4.294.967.296 unikke adresse, hvoraf mange er reserverede til specielle formål, såsom lokale netværks- eller multicast-adresser. Dette reducerer antallet af adresser der kan allokeres som offentlige internetadresser. IPv6 adresácia. Najdramatickejšou zmenou IPv6 oproti IPv4 je dĺžka sieťovej adresy. IPv6 adresy ako boli definované v RFC 2373 a RFC 2374 sú 128 bitov dlhé; toto zodpovedá 32 hexadecimálnym čísliciam, ktoré sa bežne používajú pri zápise IPv6 adries, ako popíšeme v nasledujúcom odstavci.

Internet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production in the ARPANET in 1983. It still r

IPv4 eller Internet Protocol version 4 är version fyra av internetprotokollet (IP).IPv4 var den första versionen som fick stor spridning och är idag den version som Internet i huvudsak baseras på. En IP-adress i IPv4 består av 32 bitar och begränsar protokollet till 4 294 967 296 unika adresser, av vilka flera är reserverade för speciella ändamål som exempelvis multicast och lokala nät.

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

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). Tuy nhiên, do một số được sử dụng cho các mục đích khác như: cấp cho mạng cá nhân (xấp xỉ 18 triệu địa chỉ), hoặc sử dụng làm địa chỉ quảng bá (xấp xỉ In IP networking, a private network is a network that uses private IP address space. 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. IPv4 is a connectionless protocol for use on packet-switched networks. IPv4 uses a 32-bit number address scheme allowing for total of 2 3 that reached to 4,294,967,296. As the addresses were allotted to the users and the number of addresses remained unallocated decreased. IPV4 was deployed in 1981 and prefix notation is 192.149..-24. IPv4 designates special usage or applications for various addresses or address blocks: Special address blocks Address block Address range Number of addresses Scope Description 0.0.0.0/8 -.255.255.255 16 777 216: Software Current network (only valid as source address). 10.0.0.0/8
