It is logged for a short time on the local hard drive the same as any other DNS query, but unless someone actually looks, we will not notice if you query for it. So feel free to use it for your own purposes as much as you like. We have a bit of spare DNS capacity. :)

No, sorry. We're working on it.
Of course, v6 is available on most other Akamai products.
And if someone wants to pay us for v6 on whomai..... :)
