In this issue, the editor will bring you about how to configure IPv6 addresses in Linux. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Linux supports IPv6 after kernel version 2.2.0. Check whether the / proc/net/if_inet6 file exists to determine whether your system supports IPv6.

If not, try the following command to load the IPv6 module:

# modprobe ipv6

After successfully loading, you can use the IPv6 environment, and the system will automatically obtain the IPv6 address.

IPv6 related commands:

# ifconfig eth0 inet6 add 2001:da8:2004:1000:202:116:160:41/64 (manually add and configure fixed IPv6 address)

# route-An inet6 add default gw 2001:da8:2004:1000::1 (add default route)

# ping6 ipv6.scau.edu.cn

PING ipv6.scau.edu.cn (2001:da8:2004:1000:202:116:160:48) 56 data bytes

64 bytes from 2001:da8:2004:1000:202:116:160:48: icmp_seq=0 ttl=64 time=0.020 ms

64 bytes from 2001:da8:2004:1000:202:116:160:48: icmp_seq=1 ttl=64 time=0.019 ms

64 bytes from 2001:da8:2004:1000:202:116:160:48: icmp_seq=2 ttl=64 time=0.014 ms

This display indicates that IPv6 has been configured successfully.

Linux Settings isatap Tunnel configuration IPv6

The Linux settings are as follows:

Ip tunnel add sit1 mode sit remote 192.168.253.49 local a.b.c.d

Ifconfig sit1 up

Ifconfig sit1 add 2001:da8:2004:2301:0:5efe:a.b.c.d

Route-An inet6 add:: / 0 fe80::5efe:192.168.253.49

Note: please use your real IPv4 address instead of the a.b.c.d above

After ifconfig is configured, you should see a V6 address prefixed with 2001:da8:2004:2301, hostid is 5efe:a.b.c.d, where a.b.c.d is your real IPV4 address.
