Accepted Answer

Edit the file with the following command.  
```
sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0
```

Put the following settings at the end of the file.  
```
# IPv6 connect (blog.risupu.jp/?p=264)
IPV6_AUTOCONF=yes
```

After saving the file, restart the network service with the following command.  
```
sudo systemctl restart network
```
