The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. Its main function is to translate easily memorized domain names (for example, to numerical IPv4 or IPv6 addresses.

The DNS distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. The DNS also defines the DNS protocol, a detailed specification of the data structures and data communication exchanges used in DNS, as part of the Internet Protocol suite.

The DNS client module is part of the HCC MISRA-compliant TCP/IP stack, as shown in the Networking Overview diagram, and is designed specifically for use with it.

  • Conforms to the HCC Advanced Embedded Framework.
  • Complies with the HCC MISRA-compliant TCP/IP stack.
  • Designed for integration with both RTOS and non-RTOS based systems.
  • Connects to all standard DNS servers.
  • Compliant with RFC 1034, RFC 1035RFC 2874, and RFC 3596.
