Abstract: Various arrangements for performing secure domain name system (DNS) routing are presented. A secure signature may be generated using an internet protocol (IP) address of an authorized device. An encoded character string may be generated that comprises the IP address. The domain name server may receive a request for an IP address mapped to the hostname. The hostname may be validated using the secure signature. The IP address of the authorized device may be decoded from the encoded character string at least partially in response to the hostname being validated by the domain name server. The IP address decoded from the encoded character string may be transmitted at least partially based on the hostname being validated and the request for the IP address.
