There's a hierarchy to DNS servers, and, well, it'd take some doing to supplant the root servers. -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEBcqaUD8uEzVNxUrujhHd8xJ5ooEFAlywbf0ACgkQjhHd8xJ5 ooE7jggAnGr7QcTmwefCnp5JFkm3txcGErf3C0B5BYJOIaGHwHDHjWVcFDqdrfX+ 4FNDgIWt/cV+DPngWQHMCfmP6aVv72DMlpvWoHdhcNYrmTo7k6zoCz3JPaugNqSV UHCuRWxInPchZzD6fLlRg6OT8vtX09mYP1/7NUNm6rmYk2yw7RBX0rzRN9y7IaDl iSXZKby0SCUGvmh2rR30ZrF7izW4lqVBzTaHsijh6TLrKoqvFJtp47WMeYHDJG/p 54i/DglDmMkqbdTKPt4PGDBwhlH6D4S/kUNHO8t5kDUwMASqvZuPo5zOFvdpxIyJ Oy0uOSZyczmm5l3InmIyangMY/Rnww== =x5a9 -----END PGP SIGNATURE----- -- |_|O|_| |_|_|O| Github: https://github.com/dpurgert |O|O|O| PGP: 05CA 9A50 3F2E 1335 4DC5 4AEE 8E11 DDF3 1279 A281
