Add IPV6 Print

Activating IPv6 addresses varies by operating system. Please find the section below for the operating system installed on your server and follow the directions carefully to ensure the IPs are properly configured. If your operating system is not listed here, you will need to consult your OS documentation for instructions on configuring IPv6 addresses. We cannot provide IP configuration support for unsupported operating systems.

If you are experiencing difficulty for any reason, please open a new ticket with the IPs department, and include the information necessary to log into your server remotely. We'll be happy to assist you in adding the addresses to your server.

In the sections below, replace the bracketed text (remove the brackets) with the information provided above. The value of the Prefix Length is the number after (not including) the slash in your IP range.

The Address may be anything within your assigned block besides the router address. For more information on IPv6 formatting and numbering, please see:

Please note that on Linux, FreeBSD or MacOS systems, you will need to use the "ping6" utility to ping or "traceroute6" utility to traceroute to an IPv6 address. In Windows, the usual "ping" and "tracert" utilities recognize IPv6 addresses.

CentOS, Fedora, Red Hat Linux, and variants

Edit /etc/sysconfig/network and update the NETWORKING_IPV6 line to read:

Edit /etc/sysconfig/network-scripts/ifcfg-eth0 and verify or add the following lines:

If these lines do not exist, see http://steadfast.net/ipv6-me/ for information on determining the correct values.

To add additional IPv6 addresses, insert this additional line in the same file:

You may enter as many as you like, separated by spaces.

Now run the following command to apply the configuration:

Debian, Ubuntu, and variants

Edit /etc/network/interfaces and verify or add the following lines:

If these lines do not exist, see http://steadfast.net/ipv6-me/ for information on determining the correct values.

To add additional IPv6 addresses, insert this additional line in the same file immediately following the gateway:

You may include as many lines as you like.

Now run the following command to apply the configuration:

FreeBSD

Run 'ifconfig' to identify the name of your interface. It is often fxp0 or em0 or nfe0 and almost always ends with a zero.

Edit /etc/rc.conf and verify or add the following lines:

If these lines do not exist, see http://steadfast.net/ipv6-me/ for information on determining the correct values.

To add additional IPv6 addresses, insert this additional line in the same file:

You may include as many lines as you like, but for each additional line, increment the number after "alias" (such as "alias1", "alias2").

Now run the following command to apply the configuration:

If you receive the message:

Try changing the line in /etc/rc.conf to:
