Abstract
Methods and apparatuses for handling raw DNS queries or DNS queries that generate responsive DNS records from a DNS server that are not recognized or decodable by a DNS client are described. The DNS client may receive a DNS query from an application and provide a numerical IP address and one or more DNS records for a given domain name to the application. In some cases, a DNS client provides an interface that enables the application to send and receive DNS queries and responses to DNS queries that use DNS functionalities and customizations that are not recognized by the DNS client. This capability allows the application to craft its own DNS queries to send and receive resulting response bytes or packets through the DNS client, while allowing the DNS queries to pass through the DNS client to make use of host system cache, policies, and settings.
