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?
You do realize that the query source address is not 8.8.8.8 when it goes to the authoritative server, right? The client sees 8.8.8.8. The authoritative server does not. The query from Google to the authoritative server will come from a unique address local to the particular instance. Owen
