An IP is a single IP address, a slice of bytes. Functions in this package accept either 4-byte (IPv4) or 16-byte (IPv6) slices as input. Note that in this documentation, referring to an IP address as an IPv4 address or an IPv6 address is a semantic property of the address, not ...
为了扩大地址空间，拟通过IPv6以重新定义地址空间。IPv4采用32位地址长度，只有大约43亿个地址，估计在...
