Methods and systems for dynamic domain name system (ddns)

A method for resolving a Domain Name System (DNS) request, comprising:

• receiving a DNS request;
• retrieving DNS resource record(s) based on in part a unique identifier, wherein the unique identifier is embedded in the DNS request;
• replying to the DNS requests with information, wherein the information is corresponding to the DNS resource record(s) retrieved if the DNS resource record(s) is found;
• replying to the DNS requests with information, wherein the information indicates that no DNS resource record is found if the DNS resource record(s) is not found;
• wherein the DNS resource record(s) is created based on in part at least one update message received from a network node

A network node capable of sending update messages to a first server, wherein the network node comprising:

• a plurality of network interfaces;
• at least one processing unit;
• at least one main memory;
• and
• at least one secondary storage storing program instructions executable by the at least one processor unit for:
• sending an update message to the first DNS server periodically or when a predefined event occurs,
• wherein the update message is embedded with a unique identifier and a network interface identifier,
• wherein the network interface identifier corresponds to one of the plurality of network interfaces, and
• wherein the unique identifier corresponds to the system.

A system for resolving a DNS request, comprising:

• at least one network interface;
• at least one processing unit;
• at least one main memory;
• and
• at least one secondary storage storing program instructions executable by the at least one digital processor for:
• receiving a DNS request;
• retrieving DNS resource record(s) based on in part a unique identifier, wherein the unique identifier is embedded in the DNS request;
• replying to the DNS requests with information, wherein the information is corresponding to the DNS resource record(s) retrieved if the record(s) is found;
• replying to the DNS requests with information, wherein the information indicates that no DNS resource record is found if the DNS resource record(s) is not found;
• wherein the DNS resource record(s) is created based on in part at least one update message received from a network node.
