Accordingly, a node may include processor and memory having instructions thereon, that when executed, cause the node to pair with another node. The pairing may include creating a DNS record on the node including a current address associated with the second node, this current address may be dynamically updated. The instructions may further allow the node to transmit a message to the second node, based on a resolved address from the DNS record on the first node. Authentication, dynamic message encryption and the provision of a DNS cache may further be implemented on the node. ## Claims ### Claim 1 A method for node-based DNS resolution, the method comprising: creating a first DNS record on a first node, said first DNS record comprising a second-node address; creating a second DNS record on a second node, said second DNS record comprising a first-node address; and dynamically updating, via at least one microprocessor, said first DNS record, comprising: receiving and storing a new second-node address on said first node; and designating said new second-node address as a current second-node address of said second node. ### Claim 2 (depends on 1) The method as recited in claim 1, further comprising: dynamically updating, via said at least one microprocessor, said second DNS record, comprising: receiving a new first-node address from said first node; storing said new first-node address on said second node; designating said new first-node address as a current first-node address of said first node; designating said first-node address as a previous first-node address of said first node; and storing said previous first-node address on said second node. ### Claim 3 (depends on 1) The method as recited in claim 1, further comprising storing a plurality of previous second-node addresses. ### Claim 4 (depends on 1) The method as recited in claim 1, further comprising storing a plurality of previous first-node addresses. ### Claim 5 (depends on 1) The method as recited in claim 1, further comprising resolving a second-node alias address based on said current second-node address. ### Claim 6 (depends on 1) The method as recited in claim 1, further comprising resolving a second-node alias address based on said plurality of previous second-node addresses. ### Claim 7 (depends on 1) The method as recited in claim 1, further comprising disengaging said second node from said first node based on a termination condition, said disengaging comprising erasing all records associated with said second node from said first node. ### Claim 8 (depends on 1) The method as recited in claim 1, further comprising authenticating said second node, by said first node, and based on a unique key generated by said second node and agreed by said first node. ### Claim 9 (depends on 1) The method as recited in claim 1, further comprising authenticating said first node, by said second node, and based on a unique key generated by said first node and agreed by said second node. ### Claim 10 (depends on 1) The method as recited in claim 1, further comprising modifying a DNS record on at least one other node based on a successful pairing of said first node and said second node, said modifying comprising including said current second-node address in said DNS record of said at least one other node. ### Claim 11 A system of node-based DNS resolution, the system comprising: at least one microprocessor; and at least one memory storing computer-executable instructions, said at least one microprocessor operable to access said at least one memory and execute said computer-executable instructions to: create a first DNS record on a first node, said first DNS record comprising a second-node address; create a second DNS record on a second node, said second DNS record comprising a first-node address; and dynamically update said first DNS record, said updating comprising: receiving and storing a new second-node address on said first node; and designating said new second-node address as a current second-node address of said second node. ### Claim 12 (depends on 11) The system as recited in claim 11, further comprising: dynamically updating said second DNS record, said updating comprising: receiving a new first-node address from said first node; storing said new first-node address on said second node; designating said new first-node address as a current first-node address of said first node; designating said first-node address as a previous first-node address of said first node; and storing said previous first-node address on said second node. ### Claim 13 (depends on 11) The system as recited in claim 11, wherein said dynamically updating said first DNS record further comprises storing a plurality of previous second-node addresses. ### Claim 14 (depends on 11) The system as recited in claim 11, wherein said dynamically updating said second DNS record further comprises storing a plurality of previous first-node addresses. ### Claim 15 (depends on 11) The system as recited in claim 11, wherein said computer-executable instructions are further operable to resolve a second-node alias address based on said current second-node address. ### Claim 16 (depends on 11) The system as recited in claim 11, wherein said computer-executable instructions are further operable to resolve a second-node alias address based on said plurality of previous second-node addresses. ### Claim 17 (depends on 11) The system as recited in claim 11, wherein said computer-executable instructions are further operable to disengage said second node from said first node, said disengaging comprising erasure from said first node of all records associated with said second node. ### Claim 18 (depends on 11) The system as recited in claim 11, wherein said computer-executable instructions are further operable to authenticate said second node, by said first node, and based on a unique key generated by said second node and agreed by said first node. ### Claim 19 (depends on 11) The system as recited in claim 11, wherein said computer-executable instructions are further operable to authenticate said first node, by said second node, and based on a unique key generated by said first node and agreed by said second node. ### Claim 20 (depends on 11) The system as recited in claim 11, wherein said computer-executable instructions are further operable to modify a DNS record on at least one other node based on a successful pairing of said first node and said second node, said modifying comprising including said current second-node address in said DNS record of said at least one other node.
