OpenDNS, or anyone for that matter, should never see 100.64/10 ip's. If they do, something is wrong at the source, and OpenDNS wouldn't be able to reply anyway (or at least have the reply route back to the user).

maybeopendns peers directly with such an eyeball network? and in that case maybe they have an agreement to accept traffic from the 100.64 space?

Incidentally, I hope OpenDNS considers 100.64.0.0/10 as space that can't be registered to any end-user.
