synopsis:       Stub DNS resolver with a typed RData model and value-based extension API

description:    A DNS stub resolver library for Haskell.  The IO layer is
                derived from Kazu Yamamoto's @dns@ package; what @dnsbase@
                adds is a rich set of RRtypes and a runtime-extensible
                RRtype data model with a simple configuration interface.
                .
                Every RR type's payload is modeled as a dedicated Haskell
                type — these include, for example, the recent SVCB and HTTPS
                service-binding records, with extensible up-to-date SvcParam
                coverage.  EDNS option support includes Extended DNS Errors
                (EDE) whose info-code name table is user-extensible.  Coverage
                of both widely used and historical DNS RR types is comprehensive
                — only the most marginal obsolete or experimental types remain
                unimplemented.
                .
                Applications can extend the library with any /missing/
                RRTYPEs, EDNS(0) options, SVCB and HTTPS SvcParam values.
                Application-specified data types take precedence over any
                existing or later added built-in implementations.
                .
                Extensions are registered by constructing a pure resolver
                configuration value, rather than via IO actions on mutable
                global state.  Adding custom data types to the library does not
                require a source-code fork.  See the
                <https://hackage-content.haskell.org/package/dnsbase-1.0.0.0/candidate/docs/Net-DNSBase-Extensible.html Net.DNSBase.Extensible>
                module for
                <https://hackage-content.haskell.org/package/dnsbase-1.0.0.0/candidate/docs/Net-DNSBase-Extensible.html#customRRtype detailed examples>
                .
                The library has been deployed as part of a DANE/DNSSEC survey
                for many years, and performs ~108 million queries each day,
                over approximately 3.5 hours (while also saving results to a
                database and performing some SMTP STARTTLS probes).  Domain-name
                parsing supports 8-bit RFC 1035 names directly and also
                supports pluggable @Text@-based parsers via external
                libraries, for example from the companion
                <https://hackage.haskell.org/package/idna2008 idna2008>
                package.
