Abstract
A methodology for operating an authoritative DNS server includes receiving a DNS query from a DNS client, in response to the DNS query, traversing a label tree stored in the authoritative DNS server to find a resource record that matches the DNS query, while traversing the label tree, encountering a LINK record in the label tree that is configured to redirect the traversing to a different branch of the label tree, and in response to the LINK record, redirecting the traversing to the different branch of the label tree, wherein the LINK record is a resource record type that is hidden from DNS clients and is configured to redirect for an owner of the record type and subordinates thereof.
