Raspberry Pi で IPV6 を使う

Raspberry Pi で IPV6 を使ってみました。

Raspberry Pi で　ip addr を実行

$ ip addr
（省略）
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:22:cf:fb:7b:33 brd ff:ff:ff:ff:ff:ff
    inet6 2001:240:28d5:4900:222:cfff:fefb:7b33/64 scope global dynamic mngtmpaddr 
       valid_lft 14182sec preferred_lft 14182sec
    inet6 fe80::222:cfff:fefb:7b33/64 scope link 
       valid_lft forever preferred_lft forever

そこで、他の端末から ping をかけました。

$ ping -c 3 2001:240:28d5:4900:222:cfff:fefb:7b33

ssh でログイン

$ ssh 2001:240:28d5:4900:222:cfff:fefb:7b33

nmap を使ってみました。

$ nmap -6 2001:240:28d5:4900:222:cfff:fefb:7b33
