SmartDNS is a local DNS server that accepts DNS query requests from local clients, then gets DNS query results from multiple upstream DNS servers and returns the fastest results to the client to improve network access. SmartDNS also supports the appointment of specific domain IP addresses and is highly matched to filter ads; supports DOT (DNS over TLS) and DOH (DNS over HTTPS) to better protect privacy.
Unlike all-servers for DNSmasq, SmartDNS returns the fastest resolution.
Supports Raspberry Pi, OpenWrt, ASUS router native firmware and Windows systems.
This is free and open source software.
Features include:
- Multi-Virtual DNS Server – supports multiple virtual DNS servers, different virtual DNS servers different ports, rules, clients.
- Multi-DNS Upstream Server – support for configuring multiple upstream DNS servers and querying at the same time, even if there is an exception to the DNS server, does not affect the query.
- Supports independent control of each client – support based on MAC, IP address control client using different query rules, can achieve parental control and other functions.
- Returns the fastest IP address – enables finding the fastest IP address from the list of IP addresses to which the domain belongs and returns to the client to increase network access speed.
- Support for multiple query protocols – support UDP, TCP, DOT and DOH queries and services, as well as non-53 port queries; support for sockets5, HTTP proxy queries.
- Specific domain name IP address designation – support the IP address of the designated domain name to achieve the effect of advertising filtering and avoid malicious websites.
- Domain name high performance suffix matching – supports domain suffix matching mode, simplifies filtering configuration, and filters 200,000 records time < 1ms.
- Domain name shunt – support domain shunt, different types of domain names query to different DNS servers, support better shunting of iptable and nftable; support speed failure to set the domain name results to the corresponding ipset and nftset collection.
- Supports IPv4, IPv6 dual stack – support for IPv4 and IPv6 networks, support for query A and AAAA records, support for dual-stack IP speed optimization, and support for fully disabling IPv6 AAAA parsing.
- Support for DNS64 – supports DNS64 conversion.
- High performance, less resource footprint – multithreaded asynchronous IO mode, cache cache query results.
- Mainstream system official support – mainstream routing system official software source installs smartdns.
- Cross-platform support – runs under standard Linux systems (Raspberry Pi), OpenWrt system various firmware and ASUS router native firmware. WSL (Windows Subsystem for Linux).
