Plenty of FreeBSD things are ipv6 only in the FreeBSD cluster. In particula= r if you do look at the build machines in the cluster, no ipv6 will mean no acce= ss to the build log in case of failures. I agree I don't see the reason why we should keep that ipv6 option. When off this option does not bring much value to the users as the code for apps to support ipv6 mostly reside in the libc. Actually that was my intent in 2012= to first turn it on by default everywhere and then drop the option entirely.
