IPv4 is the foundational protocol that directs data packets across the internet and other networks, having been in use since the early 1980s and remaining the primary method for routing internet traffic today. It identifies devices on a network using a 32-bit address system, which provides a finite number of unique addresses that devices can use to communicate with each other.

网际协议版本4（英語：Internet Protocol version 4，缩写：IPv4，又稱網際網路通訊協定第四版）是网际协议开发过程中的第四个修订版本，也是此协议第一个被广泛部署和使用的版本。其後繼版本為IPv6，直到2011年，IANA IPv4位址完全用盡時，IPv6仍处在部署的初期。 IPv4在IETF于1981年9月发布的 RFC 791 中被描述，此RFC替换了于1980年1月发布的 RFC 760。 IPv4是一种无连接的协议，操作在使用分组交换的链路层（如以太网）上。此协议会尽最大努力交付数据包，意即它不保证任何数据包均能送达目的地，也不保证所有数据包均按照正确的顺序无重复地到达。这些方面是由上层的传输协议（如传输控制协议）处理的。
