ccna60d/IPv6地址空间.md

在IPv6地址空间中，当前所用到的主要有4段（分别是全球单播地址、本地唯一单播地址、链路范围单播地址及多播地址），其它各段为IETF保留。

• 用到的4个地址段

  • 2000::/3

    2000:: - 3fff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

    全球单播地址空间，Global Unicast Address Space

  • fc00::/7

    fc00:: - fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

    本地唯一单播地址， Unique Local Unicast Address Space

  • fe80::/10

    fe80:: - febf:ffff:ffff:ffff:ffff:ffff:ffff:ffff

    链路上的单播地址空间， Link Scoped Unicast Address Space

  • fec0::/10

    fec0:: - feff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

    为IETF所保留, Reserved by IETF。 RFC38979中弃用，先前的站点本地范围地址前缀。

  • ff00::/8

    ff00:: - ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

    多播地址空间, Multicast, 该段中由IANA分配的地址在这里进行了登记：http://www.iana.org/assignments/ipv6-multicast-addresses/ipv6-multicast-addresses.xhtml
