专用IP地址范围
什么是私有IP地址范围?
What are the private IP address ranges?
You will find the answers to this in RFC 1918. Though, I have listed them below for you.
10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
一个常见的误解是169.254.0.0/16是私有IP地址块.这不是真的.它是本地链接，基本上是指只能在网络内使用，但不是官方的RFC1918.有关IPv4地址的其他信息，可以在 RFC 3300 中找到.
It is a common misconception that 169.254.0.0/16 is a private IP address block. This is not true. It is link local, basically it is meant to be only used within networks, but it isn't official RFC1918. Additional information about IPv4 addresses can be found in RFC 3300.
另一方面，IPv6没有与RFC1918等效的功能，但是任何形式的站点本地工作都应在fc00 ::/7中完成.在 RFC 4193 中进一步涉及到.
On the other hand IPv6 doesn't have an equivalent to RFC1918, but any sort of site-local work should be done in fc00::/7. This is further touched on in RFC 4193.
