Ipv6 firmware - Linksys WRT120N Router

Please check your MA5616 main control board and firmware version: CCUB does not support IPV6, CCUE and CCUC with V8R312 or later version support IPV6.

You may need to enable IPV6. All Comcast modem updates are done automatically. I would contact ARRIS for additional assistance. Comcast also has a helpful online community.

With the standard Linksys firmware, it does not. Some versions of the third party firmware from DD-WRT and Tomato support IPv6, but the configuration you would use depends on how you plan to use IPv6 (native, tunnel, etc).

The common ways to use IPv6 are in native mode or tunneled (6to4, 6rd or 6in4) mode.

The 'IPV4' (Internet Protocol Version 4) was designed for a world with 4 billion unique devices (desktops, laptops, netbooks, iPod Touch/Phone, IP-TV, cell-phones, et cetera).

That limit is being reached!

The newer 'IPV6' (Internet Protocol Version 6) was designed to give a unique IPV6 address for EVERY SQUARE INCH of surface of our planet.

So, if your computer is "talking" to an IPV6 device (router or modem), you should _NOT_ get "IPV6 not available". However, if your computer is "talking" using IPV4, you probably _WILL_ get the IPV6 not available" message.

No big deal. If your computer cannot "talk" IPV6, then it should "talk" IPV4.

I would try either of the following:
Go to the Belkin support web site to see whether there is a firmware update for your Belkin wireless router. If there is, download and install it per the instruction for your router.
If after updating the router's firmware the problem still occurs, try disabling IPv6 on your Mac. You do this from the "Network" icon in "System Preferences".
Once in the Network page, click the padlock in the lower-lefthand corner to unlock it with your password (if necessary).
Once the padlock is unlocked, click on the "Advanced..." button in the lower right-hand corner.
In the resulting window, click on the "TCP/IP" tab and find the "Configure IPv6:" drop down. Click on the drop-down and change the setting from "Automatically" to "Off".
Click the "OK" button
Click the "Apply" button
Click the padlock to lock the configuration if desired.
Now that IPv6 has been disabled, power-cycle the Belkin router and reboot all of your computers to see whether the network is usable by all of them.

Hi, Lets we disable your IPV6 to IP V4 only .

Do you know how to disable IPv6 in Windows Vista? Do you know it's enabled by default? It's pretty simple actually! As I know some might even want to uninstall IPv6, but you won't be able to do it as this is built-in feature in Vista kernel. Although IPv6 is developed with better security and aimed to overcome the shortage of IPv4 addresses, but there are several reasons why people still wish to disable this feature:

- Totally not going to use this IPv6 feature as it's not that popular yet and don't know how to use it
- Disabling this IPv6 feature can conserve Windows' CPU and memory resources
- Better network performance with disabled IPv6 feature
Somehow there are still some disadvantages for disabling this IPv6 feature: you will not be able to use Windows Meeting Space or any application that relies on the Windows Peer-to-Peer Networking platform or the Teredo transition technology. If you are not going to be affected by those disadvantages, let's proceed to do it:
1) Go to Start and right click on Network and then click Properties.
2) Network and Sharing Center window will appear, after that click Manage network connections.

3) Network Connections window will appears. Here you can right click on the network card that you wish to disable IPv6 and click Properties.

4) In the Local Area Connection Properties window, untick Internet Protocol Version 6 (TCP/IPv6) and click OK.
Note: This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface. You need to make change in Windows registry in order to disable the IPv6 on tunnel interface. You can stop here if don't feel like working with Windows registry. If not, proceed with Step 5.

5) Type regedit in command prompt in order to launch registry editor.

6) Registry editor will appear, proceed to locate following registry item:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents
Note: If the DisabledComponents item is unavailable, you must create it:
a) In the Edit menu, go to New, and then click DWORD (32-bit) Value.

b) Type DisabledComponents, and then press ENTER.

7) Double-click DisabledComponents, set the value as 0xffffffff (hexadecimal value) (just type ffffffff) to disable IPv6 on LAN interfaces, connections, and tunnel interfaces except the IPv6 loopback interface, finally click OK.

8) You must restart the computer for this registry value to take effect.

In regards to your question aboout IPV6 this is not standard that is supported yet. IPV6 is s future technology that his been added so that when this becomes a standard your current hardware will work with it.

So if you are having network trouble it should not be related to IPV6. If you can let me know some more about your problem I can see what I can do to address your issue.

Teredo is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 traffic when IPv6/IPv4 hosts are located behind one or multiple IPv4 network address translators (NATs). To traverse IPv4 NATs, IPv6 packets are sent as IPv4-based User Datagram Protocol (UDP) messages. This article provides an overview of Teredo—including Teredo addresses and packet structures—and detailed explanations of how communication is initiated between Teredo clients, Teredo host-specific relays, and IPv6-only hosts using the IPv4 Internet, the IPv6 Internet, Teredo servers, and Teredo relays.

Hi Poonamhe,

If your home network is a typical network with a basic consumer router and PCs you'll require a new router or firmware update, as most routers currently only support IPv4. Installation of protocols already built into Windows XP, Windows Vista, and Mac OS X. Windows Vista and Mac OS X already support IPv6 natively and Windows XP only requires the addition of an IPv6 protocol driver. It's possible to run IPv4 and IPv6 on the same systems on the same network without problems.

Because TCP/IP operates lower layers of the "OSI model", the vast majority of software applications will work perfectly without modification. Only software that makes changes to or makes direct use of lower-level TCP/IP functions will need to be replaced and this is somewhat rare.
