Open Source DNS Software

Acrylic is a local DNS proxy for Windows which improves the performance of your computer by caching the responses coming from your DNS servers and helps you fight unwanted ads through the use of a custom HOSTS file (optimized for handling hundreds of thousands of domain names) with support for wildcards and regular expressions. When you browse a web page a portion of the loading time is dedicated to name resolution while the rest is dedicated to the transfer of the web page contents. What Acrylic does is to reduce the time dedicated to name resolution for frequently visited addresses closest to zero possible. Furthermore Acrylic's sliding expiration caching mechanism and DNS silent updates are able to improve the browsing experience independently of the browser. With Acrylic you can also gracefully overcome downtimes of your DNS servers without disrupting your work, because in that case you will at least be able to connect to your favourite websites and to your email server.

Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster.

SmartDNS is a local DNS server. SmartDNS accepts DNS query requests from local clients, obtains DNS query results from multiple upstream DNS servers, and returns the results with the fastest access speed to clients, improving network access speed. At the same time, it supports the designation of specific domain name IP addresses, and high-quality matching to achieve the effect of filtering advertisements. Different from all-servers of dnsmasq, smartdns returns the resolution results with the fastest access speed. Supports Raspberry Pi, openwrt, ASUS router, windows and other devices. Supports domain name suffix matching mode, simplify filtering configuration, filter 200,000 records in less than 1ms. Supports domain name shunting, different types of domain names are queried to different DNS servers. Support standard Linux system (Raspberry Pi), various firmware of openwrt system, and native firmware of ASUS router. And support for Windows 10 WSL (Windows Subsystem for Linux).

CoreDNS is a DNS server/forwarder, written in Go, that chains plugins. Each plugin performs a (DNS) function. CoreDNS is a Cloud Native Computing Foundation graduated project. CoreDNS is a fast and flexible DNS server. The key word here is flexible: with CoreDNS you are able to do what you want with your DNS data by utilizing plugins. If some functionality is not provided out of the box you can add it by writing a plugin. CoreDNS can listen for DNS requests coming in over UDP/TCP (go'old DNS), TLS (RFC 7858), also called DoT, DNS over HTTP/2 - DoH - (RFC 8484) and gRPC (not a standard). Serve zone data from a file; both DNSSEC (NSEC only) and DNS are supported (file and auto). Retrieve zone data from primaries, i.e., act as a secondary server (AXFR only) (secondary). Sign zone data on-the-fly (dnssec). Load balancing of responses (loadbalance). Allow for zone transfers, i.e., act as a primary server (file + transfer). Automatically load zone files from disk (auto).

ExternalDNS synchronizes exposed Kubernetes Services and Ingresses with DNS providers. Inspired by Kubernetes DNS, Kubernetes' cluster-internal DNS server, ExternalDNS makes Kubernetes resources discoverable via public DNS servers. Like KubeDNS, it retrieves a list of resources (Services, Ingresses, etc.) from the Kubernetes API to determine the desired list of DNS records. Unlike KubeDNS, however, it's not a DNS server itself, but merely configures other DNS providers accordingly, e.g. AWS Route 53 or Google Cloud DNS. In a broader sense, ExternalDNS allows you to control DNS records dynamically via Kubernetes resources in a DNS provider-agnostic way. ExternalDNS' allows you to keep selected zones (via domain-filter) synchronized with Ingresses and Services of type=LoadBalancer in various cloud providers. ExternalDNS can become aware of the records it is managing therefore ExternalDNS can safely manage non-empty hosted zones.

Poweradmin is a web-based DNS administration tool for PowerDNS server. The interface has full support for most of the features of PowerDNS. It has full support for all zone types, for supermasters, full support for IPv6 and multi-language support.

Ddclient is a Perl client used to update dynamic DNS entries for accounts on 'Dynamic DNS Network Services' free DNS service.
