Acrylic DNS Proxy
A local DNS proxy which improves the performance of your computer
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
Directory/File, DNS and VHost busting tool written in Go
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. -

ExternalDNS
Configure external DNS servers (AWS Route53, Google CloudDNS and other
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. -

CoreDNS
CoreDNS is a DNS server that chains plugins
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). -

DNS-Based Host Blocking for Android
DNS-based Host Blocker (and lightweight ad blocker) for Android
This is a DNS-based host blocker for Android. In the default configuration, several widely-respected host files are used to block ads, malware, and other weird stuff. On the first start, you must manually update the hosts files (using the refresh button) before the service can work correctly (issue #1); and you must also update the hosts files yourself regularly for now. Items in the hosts and DNS servers lists can be moved around and removed) of the list using standard RecyclerView interactions (long press makes the entry movable, swipe to either side removes it). For hosts, a later entry overrides a previous entry; for DNS servers, the first server is preferred. There's also no validation of input, so DNS servers that are not valid IPv4 addresses are not rejected, neither are URLs for DNS server entries (we intend to support URLs in the future, so you can point the app to a remote list of servers). -

ddclient
ddclient updates dynamic DNS entries for accounts
ddclient is a long-standing, Perl-based Dynamic DNS client that keeps DNS records updated when your public IP changes. It supports a wide roster of DNS providers and APIs, allowing both A and AAAA updates so IPv4 and IPv6 hosts remain reachable. The client can discover your current address via network interfaces or external check services, which is crucial for NAT’d home connections. It runs as a daemon or from cron, with configurable intervals, SSL/TLS for provider communication, and robust logging to aid troubleshooting. A single configuration file defines multiple hosts, credentials, and per-record options, making complex setups straightforward. In practice, ddclient turns dynamic residential or small-office internet links into stable hostnames for VPNs, home labs, and self-hosted services. -
