net包

概述

net 包是处理网络I/O的包

常量

P地址长度

const (
    IPv4len = 4
    IPv6len = 16
)

变量

知名IPv4地址

var (
	IPv4bcast     = IPv4(255, 255, 255, 255) // 广播
	IPv4allsys    = IPv4(224, 0, 0, 1)       // 所有主机的地址 （包括所有路由器地址）
    IPv4allrouter = IPv4(224, 0, 0, 2)       // 所有组播路由器的地址
    IPv4zero      = IPv4(0, 0, 0, 0)         // 不确定地址
)

知名IPv6地址

var (
    IPv6zero                   = IP{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}
    IPv6unspecified            = IP{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}
    IPv6loopback               = IP{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1}
    IPv6interfacelocalallnodes = IP{0xff, 0x01, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0x01}
    IPv6linklocalallnodes      = IP{0xff, 0x02, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0x01}
    IPv6linklocalallrouters    = IP{0xff, 0x02, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0x02}
)

错误

var ErrWriteToConnected = errors.New("use of WriteTo with pre-connected UDP")
