      IPV6的基本情况
       我学了多少，就写多少哈。别嫌少，慢慢来。

      
     IPV6的地址类型：
       Public Address ：
      公共地址：无需解释吧，嘿嘿
       Private addresses: These are reserved IP addresses used inside organizations and are not routable in the Internet. These IPv6 addresses start with FE followed by a digit from 8 to F interval. These private IP addresses are divided into two categories:
       私有地址：园区保留的地址，不会在internet上访问到的。
       Link-local addresses    – IPs used for communications inside a physical network segment. These IPs are not routable and are used for some special tasks like neighbor discovery or autoconfiguration. These IP addresses start with FE followed by a value from 8 to B, something similar to fe80::9c62:ef40:769a:464b.
      本地链路地址：用来在本地通信的，不会被路由，开头以FE开头。之后从8到E 。例如 fe80::9c62:ef40:769a:464b.
      Site-local addresses – Even though the site-local IP addresses are deprecated, you would probably be interested to find out about them. These are IPv6 addresses similar to IPv4 private IPs. These addresses begin with FE followed by a value from C to F.
      本地站点地址： 本地的站点地址已经废弃，FE后的C到F都属于
Loopback address – We’ve talked about this earlier, an IPv6 address used for testing purposes. By pinging this IP, we redirect the traffic to the same machine (looping back the traffic).
      本机环回地址：测试目的，类似IPV4的127.0.0.1.ipv6的loopback地址是   ::1
Reserved addresses – These IPs are not leased to anyone and are reserved for future development
      保留地址：未开放
Global unicast addresses – IPs allocated to the five global RIRs. From Wikipedia:
      全局单播地址： 具体见wikipedia  “A regional Internet registry (RIR) is an organization that manages the allocation and registration of Internet number resources within a particular region of the world. Internet number resources include IP addresses and autonomous system (AS) numbers”.

      Unique Local Addresses (ULA)
A unique local address (ULA) is an IPv6 address in the block fc00::/7, defined in RFC 4193. It is the IPv6 counterpart of the IPv4 private address. Unique local addresses are available for use in private networks, e.g. inside a single site or organization, or spanning a limited number of sites or organizations. They are not routable in the global IPv6 Internet.      
     本地唯一地址：ULA   在RFC4193定义。这种地址可以在私有的局域网中使用。例如在园区
   Multicast Addresses：
   多播地址：可以看这个解释。https://wikispaces.psu.edu/display/ipv6/IPv6+Multicasting


       补充：
        linux默认不使用私有地址，设置方法：
     

[Bash shell] 纯文本查看 复制代码

echo "1" > /proc/sys/net/ipv6/conf/default/use_tempaddr
