RHCE:管理IPV6网络
IPV6地址=前缀+接口标识
网络+主机前缀相当于IPV4地址中的网络ID
接口标识相关于IPV4地址中的主机ID
NAT,DHCP
8个段
每一段16位
FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF
1111=8+4+2+1=15 16进制： 15进1
10=a
11=b
12=c
13=d
14=f
15=f
地址前缀长度用/xx表示：
2001:da8:e800:14ca:a12c:1d92:sdf:00016
IPV4/32位
IPV6/128位
双冒号只能使用一次
开头的0可以省略：
2001:0db8:0000:0010:0000:0000:0000:1000/64
2001:0db8:0:10:0:0:0:1/64
2001:0db8:0:10::1/64
组播地址

Fec0::21a:a9ff:fe15:6950 1111111011+0+0000
Fec0::/10
唯一本地地址：私有地址
Fd00::21a:a9ff:fe15:6950 11111110 0|1 +(56位) +64位
Fc00::/7 fd00::/8
接口ID:
EUI-64规范：
使用MAC-EUI-64生成接口ID
MAC唯一，所以接口ID也唯一
MAC前24bit 和低24bit 插入FFFE
Ccccccc00
反转生成64bit的接口ID
Ccccccc10
生成链路本地地址：
网络前缀：FE80::/64
MAC地址：00:11:22:aa:bb:cc
FE80::211:22FF:FEaa:bb:cc/64
组播地址：
11111111 flags scope groupID
8 4 4 112
11111111 0000 [000][0-8][E,F] GROUP ID
0001
所有节点的组播地址 FF02:0:0:0:0:0:0:1 相关于广播地址：255.255.255.255
所有路由器的组播地址：FF02:0:0:0:0:0:0:2
Ping IPV6 要加出接口名称：
Ping6 ff02::1%etho
配置IPV6地址的方法：
方法一：通过图形界面来配置
IPV6地址联网配置：
Nm-connection-editor
方法二:通过手动方式添加
添加一个新连接：
[root@foundation0 ~]# nmcli connection add con-name eno8 type ethernet ifname eno83886648
Connection 'eno8' (1d0874a4-804e-4a00-acd3-d93b37fc7f47) successfully added.
添加IPV6和IPV4地址：
[root@foundation0 ~]# nmcli connection add con-name eno6 type ethernet ifname eno67109424 \
> ip6 2001:db8:0:1::c00:207/64 gw6 2001:db8:0:1::1 ip4 192.168.2.70/16
Connection 'eno6' (3b733517-19d6-4aec-8ab6-3261b84b3088) successfully added.
查看已添加的IPV6地址：
[root@foundation0 ~]# nmcli connection show eno6 | grep ipv6
