# IPv6地址空间
|
||
|
||
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` -- 从 `2000::` 到 `3fff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`
|
||
|
||
> **全球单播地址空间，Global Unicast Address Space**
|
||
|
||
- `fc00::/7` -- 从 `fc00::` 到 `fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`
|
||
|
||
> **本地唯一单播地址， Unique Local Unicast Address Space**
|
||
|
||
- `fe80::/10` -- 从 `fe80::` 到 `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` -- 从 `fec0::` 到 `feff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`
|
||
|
||
> **为IETF所保留, Reserved by IETF**。 [RFC38979](http://www.iana.org/go/rfc3879)中弃用，先前的站点本地范围地址前缀。
|
||
|
||
|
||
- `ff00::/8` -- 从 `ff00::` 到 `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：[IPv6 Multicast Addresses](http://www.iana.org/assignments/ipv6-multicast-addresses/ipv6-multicast-addresses.xhtml)
|
||
|
||
|
||
## 全部IPv6地址空间
|
||
|
||
- `::/8` -- 从 `::` 到 `00ff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`
|
||
|
||
> **为IETF所保留, Reserved by IETF**
|
||
|
||
- `0100::/8` -- 从 `0100::` 到 `01ff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`
