Abstract: A processing system having at least one processor may obtain domain name system (DNS) traffic records of a DNS platform, the DNS traffic records associated with a source device having a first status and that is submitting DNS queries, where a first-tier DNS authoritative server of the DNS platform is configured to forward the DNS queries from the source device to at least a first second-tier DNS authoritative server of the DNS platform designated for the first status. The processing system may further detect anomalous DNS traffic records from the DNS traffic records, identify a change of the source device from a first status to a second status, based upon the detecting the anomalous DNS traffic records, and reconfigure the first-tier DNS authoritative server to redirect the DNS queries from the source device to at least a second second-tier DNS authoritative server designated for the second status.

Abstract: A system to control access to domains, servers, or content, among other things. There may be individualized or global policies. Policy servers or other devices may interface with databases, DNS servers, firewalls, programmable virtualized routers, or dynamic host configuration protocol servers, among other devices to dynamically update various policy enforcement elements.

Abstract: Aspects of the subject disclosure may include, for example, a device including a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of: receiving domain name system (DNS) record changes; identifying errors from the DNS record changes; discarding the DNS record changes responsive to the errors identified; scheduling the DNS record changes responsive to a lack of errors identified; translating the DNS record changes into protocol specific formats; and provisioning the protocol specific formats of the translated DNS record changes. Other embodiments are disclosed.
