Async::DNS

Async::DNS is a high-performance DNS client resolver and server which can be easily integrated into other projects or used as a stand-alone daemon. It was forked from RubyDNS which is now implemented in terms of this library.

Usage

Please see the project documentation for more details.

• Getting Started - This guide explains how to get started with the async-dns gem.

Releases

Please see the project releases for all releases.

v1.4.0

• Minimum Ruby version is now v3.1.
• Drop dependency on Async::IO and refactor internal network code to use IO::Endpoint and Socket directly.
• Introduce Async::DNS::Endpoint for getting the default endpoint for a given name server.
• Remove old hacks for IPv6 on Ruby v2.3.
• Introduce Async::DNS::Cache for caching DNS lookups.
• Remove logger as an option and instance variable in favour of using Console.logger directly. This is a breaking change.
• Update error logging to include more details.
• Use keyword arguments **options where possible. This is a breaking change.
• Async::DNS::StreamHandler and Async::DNS::DatagramHandler have been refactored to use IO::Endpoint and have minor breaking interface changes.
• Async::DNS::Resolver.default should be used to get a default resolver instance.
• The resolver now supports ndots: when resolving names.
• Async::DNS::Resolver#fully_qualified_name is replaced by Async::DNS::Resolver#fully_qualified_names and can yield multiple names.
• If the host system supports IPv6, the resolver will also try to resolve IPv6 addresses.
• Async::DNS::Server::DEFAULT_ENDPOINTS is removed and replaced by Async::DNS::Server.default_endpoint(port = 53).
• Async::DNS::Server#fire is removed with no replacement.
• The default Async::DNS::Server#process fails with NXDomain instead of NotImplementedError.
• Async::DNS::System implementation is updated to support IPv6 and resolv.conf options.
