It doesn't seem to be permanent in windows 11

Edit to make it permanent make sure you run the command in PowerShell as an administrator.

After what period does it reset TTL or what is the trigger for this?

I am not sure if its from a windows update but as of 04/03/25 this is not working in Win11or Win10. Not sure if others are experiencing this as well. I also ran PowerShell and CMD with admin rights and ttl still does not change.

Indeed it didn't work today on Windows 11

Actually it worked, but I've had to set the custom TTL for IPv6 as well

netsh int ipv6 set glob defaultcurhoplimit=65
