Silly question: MacBSD.org resolves to the NetBSD site (and has an IPv6 address!).
All of my production machines have been on IPv6 for a decade now.
MacBSD.com resolves to a "catchall" IP. Both are (apparently) registered to John Klos. Oversight?
The macbsd.com domain had expired. I've set it to autorenew. Oops! Thanks, John
