Dns
This project is a Go DNS library used for implementing DNS clients and servers. It provides a toolkit for packet exchange, record parsing, and the development of custom nameservers.
The library includes a DNS server framework and a zone manager for parsing standard zone files and synchronizing data via zone transfers. It features a dedicated DNSSEC implementation library for generating cryptographic keys and validating signatures, as well as a TLS transport for encrypted connections between clients and servers.
The system covers a broad range of capabilities including DNS resolver functionality, resource record data modeling, and the administration of domain namespaces. It handles the translation of network byte streams into structured objects and supports secure communication protocols.
Features
- Authoritative Name Server Frameworks - Provides a comprehensive framework for creating nameservers that manage zone transfers and secure communication.
- DNS Protocol Libraries - Provides a complete Go library for implementing DNS clients and servers with full packet and record support.
- DNS Query Clients - Implements software components used to construct and transmit DNS queries to remote servers.
- DNS Record Resolvers - Enables requesting specific domain data from nameservers and extracting the answer section.
- Record Representation - Provides data structures for representing diverse DNS resource records, including names and types.
- DNS Server Frameworks - Provides a toolkit for building custom name servers with support for zone transfers and secure protocols.
- Reverse DNS Zone Calculation - Implements a zone manager for organizing and updating name server zone data from files or strings.
- DNS Zone Transfers - Implements full and incremental zone transfers to synchronize data between distributed DNS servers.
