5.1.12.5 Obtaining an IPv6 Address from a Broker

Contents

If you do not have a public IPv6 address that enables your system to communicate over IPv6 outside your local network, you can obtain one from an IPv6 broker. The Wikipedia IPv6 Tunnel Broker page lists several brokers and their features, such as whether they provide static addresses and the supported routing protocols.

After configuring your server host to use a broker-supplied IPv6 address, start the MySQL server with an appropriate bind_address setting to permit the server to accept IPv6 connections. You can specify * (or ::) as the bind_address value, or bind the server to the specific IPv6 address provided by the broker. For more information, see the bind_address description in Section 5.1.8, “Server System Variables”.

Note that if the broker allocates dynamic addresses, the address provided for your system might change the next time you connect to the broker. If so, any accounts you create that name the original address become invalid. To bind to a specific address but avoid this change-of-address problem, you might be able to arrange with the broker for a static IPv6 address.

The following example shows how to use Freenet6 as the broker and the gogoc IPv6 client package on Gentoo Linux.

Create an account at Freenet6 by visiting this URL and signing up:
```
http://gogonet.gogo6.com
```
After creating the account, go to this URL, sign in, and create a user ID and password for the IPv6 broker:
```
http://gogonet.gogo6.com/page/freenet6-registration
```
As root, install gogoc:
```
shell> emerge gogoc
```
Edit /etc/gogoc/gogoc.conf to set the userid and password values. For example:
```
userid=gogouser
passwd=gogopass
```
Start gogoc:
```
shell> /etc/init.d/gogoc start
```
To start gogoc each time your system boots, execute this command:
```
shell> rc-update add gogoc default
```
Use ping6 to try to ping a host:
```
shell> ping6 ipv6.google.com
```
To see your IPv6 address:
```
shell> ifconfig tun
```
