IPV6 Question

Topic

New Reply

Every week or so my ISP disconnects and reconnects my IPV6. I just noticed that it is no longer there, just the IPV4.  The ISP sends the “lease” to the router for both the IPV4 and sends also IPV6 more frequently than the IPV4.

Now, I use Norton and perhaps something has to do with the firewall?

I noticed that just happened with the latest signal that the ISP sent this past week.

1. Could be the router
2. Could be that the settings changed with upgrades in the neighborhood
3. Could be that the firewall is blocking it
4. I checked the driver, says the driver is the correct one for windows 10.
5. Should I worry?

Thanks for the information

With IPv6 “down”, are you having any connectivity issues?

Do you have any applications or destinations that require the use IPv6 at the IP layer?

Do you have a test tool or application that can force using IPv6 only at the IP communication layer?

Not sure of problem scope or the guilty party without running some tests.

I do not have any need for IPV6, I just noted that in checking in Norton, the IP address for IPV6 was lost. Was thinking it was the AV Software or a driver or even the router.

There are no connectivity issues with IPV4.

I happened to look at the network connections and saw that it was missing.

Could be the ISP as they were working in the neighborhood.

I had a reboot of the internet last week, just noticed it now after the reboot in the evening when they sent the signal.

Is your ISP one that is listed at https://www.dslreports.com/forums/all ? If so, survey the threads in that forum to see if anyone else has encountered this problem.

I checked the website and it appears some upgrading was done in the area.

Therefore, it is the service, or the router.

What does this mean in the event viewer:

WLAN Extensibility Module has Stopped

Check your internet address using a different method to be sure Norton is correct.

Norton is the antivirus; I am wondering if the AV has placed a firewall on IPV6 or the router or the WAN/WLAN.

Or it is the router itself and the way the ISP is broadcasting in this area now.

Norton has nothing to do with ISP assigned V6 addresses on your router.
Are you sure you are looking at your internet IP address and not the local one?

My ISP address does not show an IPV6, just IPV4.

Since I am not sure what you are asking, the laptop show the wifi connection to the router and shows the connection to the ISP. I see the IPV4 physical address, IPV4 address and mask, gateway, default gateway server and servers.

And then a local IPV6 address but no connection to the gateway.

So, either the ISP has changed settings and I no longer connects to IPV6 or something is outdated like the router, blocking it, a firewall, or just does not connect. I thought it might be the wireless card and needing an update with a driver.

I’m not sure if I really need to pursue it, I happened to check it and wanted to know if it is something I should be concerned about.

Your ISP is not doing this, it’s local so you can ignore it. (Sounds like Norton is trying to justify the cost of a license by giving you irrelevant information.)

So the reason I do not connect to the IPV6 is:

1. could be antivirus software
2. could be the local address is not recognized
3.  could be the WLAN driver or wifi card
4. none of the above

When I search for the ISP address I come up with the IPV4 but not the IPV6.

When I search in my hardware and connection properties, I see an IPV6 address but I am not connected to it. Not sure I should even be concerned, but did have it before.

Was thinking it was the last windows 10 update and or the AV software settings.

In the AV settings it says the firewall settings block inbound and outbound ICMPV6: Direction IN/Out, computer, local subnet, communications: Specific, Protocol TCP

Allow: Outbound ICMPV6, direction outbound, computer. Any, Communications, protocol, ICMPV6

Some ISPs don’t offer IPV6, only IPV4.

Windows 10 and above will automatically assign an IPV6 address on local network cards. This is not the same as an internet IPV6 address.

If you have only one PC you can safely ignore IPV6 addresses. If you have multiple machines and share disks / printers between them, you may need IPV6 for the connections.
