Testing Over 1000 gTLDs for EDNS0

In advance of open source DNS developers "DNS Flag Day", ISC's EDNS0 tester is applied across 1200+ zones. In preparing so many delegations across so many zones, a lot of interesting comments can be made regarding how zones, name servers and addresses are mixed, as well as the results of the original goal, testing EDNS0 protocol deployment.
