Automated IPv6 Configuration

Due to the huge growth of the internet users, mobile users using internet connection makes development and implementation of IPv6 as an alternate solution. IPv6 is a long anticipated upgrade to the internet’s main communication protocol, which is called IPv4. The current address space provided by IPv4, with only4, 294, 967, 296 addresses. Nowadays IPv6 tunneling over IPv4 are widely used to form the global IPv6 Internet. The IPv6 128-bit address scheme it should provide enough addresses for everyone’s computer. Tunneling provides a path to use an existing IPv4 to IPv6. This paper describes typical IPv6 tunneling and tunnel broker’s deployment in real IP networks. In the deployment of IPv6, it is a well adopted practice that IPv6 networks are interconnected via IPv6 over IPv4 (IPv6/IPv4) tunnels.

TUNNEL BROKERS

There are a variety of tunnel brokers that provide their own implementations based on different business goals. For example, one tunnel broker product on the market is called gogo server (formerly Gateway6).It’s free client utility tunnel broker.

1. GOGO CLIENT IPv6 CONNECTIVITY

Go to http://gogo6.com/. At the upper right of the page, click "Freenet6". On the next page, click Sign Up. Fill in the form to create an account. You will have to read your email and click a link to verify your account, and also fill out a profile form. Go to http://gogo6.com/ and, at the top of the page, click "Freenet6". Your name should appear at the upper right of the page Freenet has recorded your ID with a cookie. In the "Freenet Services" section, click the Download button. The next page offers several versions to download. Download the "gogoCLIENT - Basic version" and install it with the default options. Now you need to create a Freenet6 Tunnel account. In your browser, on the "Download" page, at the top, click the "Freenet6" link. Scroll down to the "Freenet6" section and click the "Learn more" link, as shown below on this page.

On the next page, scroll down to the "Getting started" section, and click the "here" link, as shown below on this page. Fill out the form to get a Freenet6 account.

When the gogoCLIENT is installed and running, click the "Advanced" tab, and select a "Tunnel Mode" of "IPv6-in-UDP-IPv4 Tunnel (NAT Traversal)" as shown below on this page. Click "Apply".

In the gogoCLIENT window, click the "Basic" tab. Change the "Server Address" to authenticated.freenet6.net. In the middle of the window, click the "Connect Using the Following Credentials" button. Enter your Freenet6 username and password. Click the "Connect" button. A box will pop up asking "Save changes before connecting?” Click Save.

Click the "Status" tab. When it connects, you should see a long IPv6 "Local Endpoint Address", as shown below on this page. If you cannot connect, you may have to adjust your router or firewall to allow UDP port 3653.

Effectively, you load on a driver on your client system, and you establish a tunnel from your system, through the Tunnel Broker’s network to access servers and services, things like http://ipv6.google.com over IPv6.

For the individual or small business that doesn’t want to setup its own DirectAccess server and relay or routing setup, the Tunnel Broker can drastically simplify the process. Say for example you want to access the latest IPv6 Facebook site from your home office, but your DSL provider doesn’t have IPv6 support yet and your company hasn’t setup IPv6 routing on their end, you can simply download the Tunnel Broker drivers, install them on your home system, and within about 10 minutes, your home system is now configured using IPv6 to Facebook’s IPv6 site.

2. HURRICANE ELECTRIC IPv6 CONNECTIVITY

This is also one of the free IPv6 tunnel broker. Go to http://tunnelbroker.net. At the left corner of the page, click register. On the next page fill the form to create an account. Your new login username and password will be sent to your registered email address. After login the user account click “Create regular tunnel” IPv4 endpoint enter your viewing IP, select anyone server closest to you? Click Submit. On the next page will show tunnel detail.
