So in how many of the 196 or so extant countries does 8.8.8.8 resolve to
a host which, when it sends a query up the chain, appears to be in the
same country as the machine that made the original query?
How does a company know that another instance of 8.8.8.8 has been turned up or
down or re-peered, causing a shift in the mapping of DNS queries to countries/
states?
