Windows 10: Login History showing IPv4 address instead of IPv6

Hi a couple of months ago I was having an issue where all of a sudden an IPv6 address was being logged on my Login history page whenever I logged in instead of the usual IPv4 address. This became more and more common until it just became the norm where it would show the current IPv6 address every time.Now for some reason it is starting to show my IPv4 address again. And not consistently either. I have changed nothing on my end and I do not understand why it is going back and forth, is this something I should be concerned about, whether on a security level or otherwise?

Prefer ipv4 over ipv6

hi,

I want to set ipv4 to be preferred over ipv6, the other day i've used the tips from this Ping returns IPv6 Address, ping IPv4 in Command Prompt - TheITBros on my 2 windows10 computers and everything worked out great!

Now, i just did a win10 update and i noticed that that no longer works even by doing the very same "command" and it kinda gets ignored. Did they just remove the functionality?

This is what i get from netsh interface ipv6 show prefixpolicies (i don't get the longer list anymore but just these):





So it seems to be preferring ipv4, yet when i ping my site (available on both ipv4 and ipv6), i get output with ipv6, same as google.com - the other day it was working nicely to ipv4 and i only used these 2 commands they suggested:

netsh interface ipv6 set prefix ::/96 60 3

netsh interface ipv6 set prefix ::ffff:0:0/96 55 4

what's going on? I don't want to disable it completely (i know i can disable it from the router or from the network card properties, i just want to de-prioritise it)

[Version 10.0.19044.1387]

thank you,
Gabrio

might have answered myself, i've added

netsh interface ipv6 add prefixpolicy ::/0 40 1

and it did the trick... i wonder if it will stick now

 

Web Address System Faces Changes; We Will Run Out of IPv4 Domains by 2011

Well this is an absurd, IPv6 is made to work with IPv4, actually every IPv4 address has tons of IPv6 addresses reachable through 6to4. Yes eventually ipv4 will die, but your routers will die from old age sooner...

 

Connectivity (IPv4/IPv6): Disconnected

Hi,



Thank you for writing to Microsoft Community Forums.



Ideally this Connectivity (IPv4/IPv6): Disconnected, means that the devices in not in use or not connected and it could be any device for example, Ethernet, WIFI, Bluetooth or Local Area Connection.



If you are using WI-FI for internet connection then Ethernet will show Connectivity (IPv4/IPv6): Disconnected.
