Abstract
Systems and methods are described to enable a DNS service to encode information into a network address to be advertised by the DNS service. Information encoded by a DNS service may include, for example, an identifier of a content set to which the network address corresponds (e.g., a domain name) and validity information, such as a digital signature, that verifies the validity of the network address. On receiving a request to communicate with the network address, a destination device associated with the network address may decode the encoded information within the network address to assist in processing the request. In some instances, the encoded information may be used to identify malicious network transmissions, such as transmissions forming part of a network attack, potentially without reliance on other data, such as separate mappings or contents of the data transmission.
