Abstract
Systems and methods are described herein for providing proxy mechanisms for DNS services, such as resolving DNS requests. In some embodiments, the systems and methods establish a Proxy DNS module at a DNS resolver of an internet service provider, and access, with the proxy DNS module, DNS queries destined for a public name server. The name server may be accessible by the DNS resolver via a publically-accessible network. Further, the systems and methods may route the accessed DNS queries to a private name server associated with the proxy DNS module and accessible via a private communications channel, and receive, from the private name server and via the private communications channel, IP addresses associated with the DNS queries.
Claims20
A method performed by a proxy DNS module associated with a DNS resolver of an internet service provider, the method comprising:
- accessing, with the proxy DNS module, DNS queries destined for a public name server, wherein the public name server is accessible by the DNS resolver via a publicly-accessible network;
- routing the accessed DNS queries to a private name server associated with the proxy DNS module and accessible via a private communications channel;
- receiving a master file of the private name server with IP addresses associated with the DNS queries;
- and
- receiving, updates to the master file from the private name server with new or changed information to the IP addresses via the private communications channel.
A proxy DNS module associated with a DNS resolver of an internet service provider, the proxy DNS module comprising:
- one or more processors configured to:
- access, with the proxy DNS module, DNS queries destined for a public name server, wherein the public name server is accessible by the DNS resolver via a publicly-accessible network;
- route the accessed DNS queries to a private name server associated with the proxy DNS module and accessible via a private communications channel;
- receive a master file of the private name server with IP addresses associated with the DNS queries;
- and
- receive, updates to the master file from the private name server with new or changed information to the IP addresses via the private communications channel.
A non-transitory computer-readable medium whose contents, when executed by a DNS proxy module associated with a DNS resolver, cause the DNS proxy module to perform a method for providing domain name system (DNS) services, the method comprising:
- accessing, with the proxy DNS module, DNS queries destined for a public name server, wherein the public name server is accessible by the DNS resolver via a publicly-accessible network;
- routing the accessed DNS queries to a private name server associated with the proxy DNS module and accessible via a private communications channel;
- receiving a master file of the private name server with IP addresses associated with the DNS queries;
- and
- receiving, updates to the master file from the private name server with new or changed information to the IP addresses via the private communications channel.
