Claim 7:
8. A method comprising:
effecting, by a first primary Domain Name System (DNS) server, a change to a record in the first primary DNS server, wherein the first primary DNS server and a second primary DNS server autonomously operate in a first group of DNS servers, wherein each primary DNS server in the first group has an ability to make changes to records independently from other primary DNS servers in the first group;
wherein to propagate the change:
the first primary DNS server signs the change with a first private key to validate the change,
the first primary DNS server generates one or more first DNSKEY records that records the change,

effecting, by the second primary DNS server, the change to a second record in the second primary DNS server,
wherein to propagate the change:
the second primary DNS server signs the change with a second private key to validate the change,
the second primary DNS server generates one or more second DNSKEY records that records the change,

wherein to ensure a DNSKEY record request routed to any primary DNS servers autonomously operating in the first group is filled:
the one or more second DNSKEY records and the one or more first DNSKEY records are exchanged between the first primary DNS server and the second primary DNS server.
