So when you add in large ccTLDs like .cn .de .uk the numbers are broadly consistent. With respect to jck's comment, these are all 2ld or perhaps slightly below for names like foo.co.uk. It obviously wouldn't be hard to come up with a scheme that allocated eight billion names for people in some DNS structure. After all, we came up with names for all 340 undecillion IPv6 addresses. But the hard part would be assigning and managing them. In any event, I agree with other comments that the DNS it not likely to be a good place to store info about people since everything in it is public. R"s, John
