Windows 10: Is It Safe to Disable IPv6 in Favour of IPv4

I just received a new modem/router, and I'm assuming because of the upgrade, my laptop and PC now run on IPv6, according to Event Viewer > NetworkProfileI understand IPv6 is technically better but it spawns a bunch of connections in Netstat, with similar addresses to the IPv6 address; however, they don't match, and are always connecting to Search, as well as asusns on either Port 443 or Port 80I'd like to put things back the way they were, so I went to Control Panel > Network and Sharing Center > Change Adapter Settings and went to Properties of both the Wifi and Ethernet to uncheck "

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 - - - Updated - - - 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

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.
