Yes, and if you have a well-designed network that has IPv4 follow the same packet path as IPv6, OSX will happily flip-flop back and forth between IPv4 and IPv6 between http request to the same server. Not overly deterministic, and not helpful when looking for "sometimes it does not work" errors (like, an Apache ACL mistakenly permitting only one of the protocols). Gert Doering -- NetMaster -- have you enabled IPv6 on something today...? SpaceNet AG Vorstand: Sebastian v. Bomhard Joseph-Dollinger-Bogen 14 Aufsichtsratsvors.: A.
