Dnsguide
dnsguide is a software implementation of the DNS protocol designed to handle queries and responses between clients and nameservers. It functions as a recursive DNS server and network service tool for managing the resolution of domain names within local or wide area networks.
The project provides a framework for building a custom DNS server, incorporating recursive resolution logic and stub resolver integration to translate hostnames into IP addresses. It is designed for implementing the DNS protocol from scratch to facilitate network protocol learning and custom name resolution.
The implementation covers binary packet serialization, UDP-based packet handling, and iterative query logic. It also includes an in-memory DNS cache to manage resolved records.
Features
- Recursive DNS Resolution - Provides a full implementation of recursive DNS resolution to translate domain names into IP addresses.
- Recursive DNS Resolvers - A domain name system server that implements stub resolution and recursive logic to translate hostnames into IP addresses.
- DNS Protocol Implementations - Provides a complete software implementation of the DNS protocol for handling queries and responses.
- Iterative Query Logic - Implements the iterative logic required to traverse the DNS hierarchy from root servers down to authoritative servers.
- DNS Servers - Implements a functional DNS server capable of resolving hostnames to IP addresses.
- Stub Resolver Integration - Integrates stub resolver capabilities to forward queries to external DNS servers when local resolution fails.
- In-Memory Caches - Provides an in-memory cache to store resolved DNS records and reduce query latency.
- Domain Name Systems - Implements a system based on the Domain Name System for mapping human-readable names to network addresses.
- Network Protocol Implementations - Implements the DNS protocol from scratch as a means of exploring network protocol architecture.
- DNS Packet Handling - Handles low-latency DNS queries and responses using UDP-based packet processing.
- Binary Serialization - Implements binary serialization to convert DNS message structures into raw byte streams for network transmission.
