This package implements an API for accessing
the Domain Name Service (DNS)
resolver service via the standard libresolv
system library (whose
API is often available directly via the standard libc
C library) on
Unix systems.
This package also includes support for decoding message record types
as defined in the following RFCs:
RFC 1035: Domain Names - Implementation And Specification
RFC 1183: New DNS RR Definitions
RFC 2782: A DNS RR for specifying the location of services (DNS SRV)
RFC 2915: The Naming Authority Pointer (NAPTR) DNS Resource Record

RFC 6844: DNS Certification Authority Authorization (CAA) Resource Record
RFC 6891: Extension Mechanisms for DNS (EDNS(0))
RFC 7553: The Uniform Resource Identifier (URI) DNS Resource Record
For Windows, the package windns
provides a compatible subset of this package's API.
