what does that mean? boot starts ipv6 and then it is disabled when i log in? can i remove ipv6
?
Do the numbers in every start of a line means time, seconds?

thanks

Numbers at the start of the line are time in seconds since the last boot. In network manager for your connection do you have IPv6 set to ignore?
