I'd like to add that disabling IPv6 with PPP on 21.02 will not fully 
disable IPv6 as per jow's tip here [1], would be neat if that could be 
fixed (and backported to a .1, this is not a showstopper for 21.02 
final in any way). Just wanted to put it on the radar. An unintentional 
side effect with a local ISP here is that it breaks IPv4 a well.

Cheers

Stijn
