No IPv6 in System Information -> Network

[treysis]

Bug report

Describe the bug

Here is a clear and concise description of what the problem is:

Looking at System Information -> Network, Kodi only shows the IPv4 address of the system, not the IPv6 addresses.

Expected Behavior

Here is a clear and concise description of what was expected to happen:

Kodi should show also IPv6 addresses, and not only IPv4.

Your Environment

Used Operating system:

• Windows

• Operating system version/name: Windows 10 Pro x64

• Kodi version: 19/Matrix, 20/Nexus

note: Once the issue is made we require you to update it with new information or Kodi versions should that be required.
Team Kodi will consider your problem report however, we will not make any promises the problem will be solved.

Just because I'm interested....Does Kodi actually show an IPv4 address at your setup or is that section simply empty and you just know that it usually shows an IPv4 at this section?

I'm asking because with current code, Kodi only shows the "first connected interface". So Kodi might probably show your IPv6 address if that's the only interface which is connected. If you have IPv4 and IPv6 configured, Kodi will search for the first interface and display whatever is found then. Think of the case where your LAN (ethernet) might be configured to use IPv6 and your WiFi interface might be configured with IPv4. Most OSs detect the WiFi adapter first

[treysis]

The device doesn't even have WiFi. All interfaces are dualstack. The correct IPv4 address is shown. There simply is no field to display the IPv6 address.

[DaVukovic]

Cool. Thanks.

Then I would say Kodi behaves correctly due to the explanation I gave above. Kodi only shows the first connected interface. If it's the one with the IPv4 address, then Kodi does everything correct.

Everything else would be an improvement for given functionally.

Can you try to configure your system in a way that the interfaces do only have IPv6 addresses and can you then confirm the correct one is shown?

[treysis]

Well, "correctly" is subjective. All my interfaces are DualStack, so they have both IPv4 and IPv6 at the same time. I tried removing IPv4 from the interface, but it will still not show the IPv6 address. So yes, it's not a real bug (well, IPv6 support in 2021 should be better).

[DaVukovic]

Well, if no IPv4 is configured and IPv6 is not shown, then I would consider this being a bug as the address should be shown regardless of the version in use.

I'll have a deeper look. Can't promise if I'm able to provide a fix, but we'll see ;)

[treysis]

Even if IPv4 is configured, it should still show IPv6, because both versions are used simultaneously.

[DaVukovic]

That would be the improvement and would be considered as a feature request. This section here is for bug reports. Feature requests should be submitted to our forums.

It is a bug if only IPv6 is configured but not shown.
It's not a bug if IPv6 is configured and also shown
It's not a bug if IPv4 and IPv6 is configured and only of them is being shown, as that's how current Kodi code is working (only showing the first connected interface).

I guess explaining it for the 2nd time now is enough ;)

[treysis]

Yes, but it is only ONE interface. One interface can have multiple IP addresses.

[growse]

FWIW, on an IPv6-only host, kodi's Network page in the System Info shows "Link: Not connected" with the MAC address, IP, subnet etc. all blank.

It is a bug if only IPv6 is configured but not shown.

Feels like this is true.

I notice this issue too, but in my case it shows the DNS server.

[treysis]

Still no change. Kodi doesn't seem to know about IPv6?

[treysis]

I was hoping this would get fixed with 20/Nexus, but nothing has changed :(
