Can you share from/to? I was told 4.2.2.2 is anycast (or otherwise geographically diverse), though I have no proof of that.
4.2.2.x are *authoritatively* multicast; I have that from someone who is involved in running recursive DNS for whatever the hell they're calling themselves this year. :-) In other news: not all 6 of those servers will always respond to ping traffic even if they're resolving; it's random; presumably they don't want anyone to get too settled into using them as a ping beacon to watching the weather on the 'net. Understandably. Cheers, -- jra -- Jay R.
