I followed the above and it boots and 'netstat -r' no longer says anything about IPv6. I found section 23.5.1 on this page: https://www.freebsd.org/doc/handbook/makeworld.html to be confusing. I'm not sure if that is out of date, but the 'make -j4 kernel' is different than make buildkernel and it says to reboot before running 'make installworld'. I'm not sure if it matters but I did 'make buildkernel ...' before 'make buildworld'. Then I installed both and then rebooted. I tried to get away with just rebuilding the kernel and installing that, but that didn't work. Anyway, I'm glad I was able to do this and bring it up in the hope that ground-up entrepreneurs will not be dismissed by FreeBSD. IPv6 is a headache for mom & pop shops.
