Abstract
This disclosure describes techniques including, by a domain name service (DNS), receiving a name resolution request from a client computing device and, by the DNS, providing a nonce to the client computing device, wherein a service is configured to authorize a connection request from the client computing device based at least in part on processing the nonce. This disclosure further describes techniques include a method of validating a connection request from a client computing device, including receiving the connection request, the connection request including a nonce. The techniques further include determining that the nonce is a valid nonce. The techniques further include, based at least in part on determining that the nonce is a valid nonce, authorizing the connection request and disabling the nonce.
