Abstract
In one embodiment, a code authentication service maintains a mapping of uniform resource locators and key information embedded into codes. The code authentication service receives, from a requesting device, a domain name system resolution request for a particular uniform resource locator. The code authentication service determines, based on the mapping, whether the domain name system resolution request is associated with valid key information for the particular uniform resource locator. The code authentication service provides, to the requesting device, a domain name system resolution response that indicates an address associated with the particular uniform resource locator, when the code authentication service determines that the domain name system resolution request includes valid key information for the particular uniform resource locator.
