Serverless Dns
This project is a serverless DNS resolver and DNS over HTTPS gateway that translates domain names into IP addresses. It functions as an edge computing DNS filter designed to encrypt queries, prevent tampering, and improve user privacy on browsers and mobile devices.
The system distinguishes itself by operating as an edge DNS traffic monitor that logs and analyzes request patterns in real time. It utilizes curated blocklists at the network edge to block malicious domains and trackers.
The software provides capabilities for private DNS filtering, network traffic monitoring, and the management of firewall rules to restrict internet access. It allows for the configuration of upstream resolvers and the generation of encrypted endpoints based on specific rules.
The project is written in JavaScript and is designed for deployment on edge platforms.
Features
- DNS Resolvers - Functions as a serverless DNS resolver that converts human-readable web addresses into IP addresses.
- DNS-over-HTTPS Servers - Functions as a secure gateway that serves DNS queries over HTTPS to prevent tampering.
- Edge Request Processing - Processes DNS queries at the network edge to minimize latency and distribute load across global serverless providers.
- Serverless Function Executions - Runs DNS resolution logic in short-lived, automatically scaling serverless functions without persistent server state.
- Serverless Deployment - Deploys the DNS resolver to distributed serverless platforms to process requests closer to the user.
- Multi-Protocol DNS Resolvers - Translates domain names into IP addresses while maintaining compatibility with secure DNS transport protocols.
- Serverless Implementations - Implements a DNS resolver deployed on edge platforms like Cloudflare Workers and Deno Deploy.
- Serverless DNS Resolvers - Provides a DNS resolver that runs on edge platforms to translate domain names into IP addresses.
- DNS Filtering - Blocks malicious domains and trackers by filtering DNS requests using curated blocklists.
- Edge-Based DNS Filtering - Operates as a privacy-focused filter that blocks malicious domains using curated blocklists at the network edge.
- Encrypted DNS Resolvers - Provides encrypted DNS endpoints using protocols like DNS-over-HTTPS to protect user privacy.
- Custom DNS Resolvers - Provides a secure DNS resolver that translates domain names into IP addresses using encrypted protocols.
- Malicious Domain Filtering - Intercepts DNS queries and uses curated blocklists to prevent the resolution of malicious or tracking domains.
- DNS Configuration Generators - Generates unique encrypted DNS-over-HTTPS endpoints based on selected rules and blocklists.
- Upstream Resolver Pinning - Directs network requests to specific external upstream resolvers via environment variable configuration.
- DNS Routing Overrides - Maps specific domains to designated upstream resolvers on serverless infrastructure to override global settings.
- Private DNS Configurations - Allows mobile devices to resolve domain names using private, encrypted methods to improve internet privacy.
- Blocked Query Logging - Captures and aggregates DNS request data into logs to identify blocked connection attempts and network patterns.
- Network Content Filters - Restricts outgoing network traffic and DNS queries based on custom rules to prevent access to unwanted content.
- DNS Query Monitoring - Analyzes DNS resolution requests in real-time to identify blocked requests and network patterns.
- DNS Traffic Monitoring - Stores query logs and generates reports to track DNS request patterns and server activity over time.
- Network Traffic Monitoring - Logs and analyzes outbound network traffic and DNS query patterns in real time.
