这在诸如以太网之类的广播链路网络环境中会非常高效,在此类网络环境中,会同时连接多台设备。在运行 IP 的以太网络中,还会利用地址解析协议(Address Resolution Protocol,ARP)将直连主机的 IP 地址解析为相应的数据链路层地址。 目前,IP地址分为两类:IPv4地址和IPv6地址。在IPv6未得到正式启用之前,目前在用的IPv4...

Internet Protocol version 4 was released in 1983, and is the standard for all packet-switch-based networks in use today. IPv4 uses a 32-bit address space that gives an upper limit of 4,294,967,296 (4.3 billion) unique logical IP addresses. A large number of these available IP addresses...
