NextDNS protects you from all kinds of security threats, blocks ads and trackers on websites and in apps and provides a safe and supervised Internet for kids, on all devices and on all networks. Determine your threat model and fine-tune your security strategy by enabling 10+ different types of protections. Use the most trusted threat intelligence feeds containing millions of malicious domains, all updated in real-time. Go beyond the domain, we analyze DNS questions and answers on-the-fly (in a matter of nanoseconds) in order to detect and block malicious behavior. With usually only a few hours between domain registration and the start of an attack, our threat intelligence system is built to catch malicious domains earlier than classic security solutions. Block ads and trackers on websites and in apps, including the most devious ones. Use the most popular ads & trackers blocklists, millions of domains all updated in real-time.

Blocky is a fast, lightweight DNS proxy and network-wide ad blocker designed for home labs and small networks that want Pi-hole-like filtering with more flexible DNS routing and modern protocol support. It blocks DNS queries using external deny lists while also supporting allow lists, and it can scope policies by client groups so different devices or households can have different rulesets. Unlike a single-purpose blocker, it supports advanced DNS behavior such as conditional forwarding and custom resolution for specific domains, letting you shape traffic in ways that fit split-horizon DNS, internal services, or privacy-focused upstream strategies. Performance is a major focus, with configurable caching, prefetching, and the ability to use multiple upstream resolvers simultaneously to reduce latency and avoid single points of failure.

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).

Twisted is an event-based framework for internet applications, supporting Python 3.6+. It includes modules for many different purposes. Twisted supports all major system event loops, select (all platforms), poll (most POSIX platforms), epoll (Linux), kqueue (FreeBSD, macOS), IOCP (Windows), and various GUI event loops (GTK+2/3, Qt, wxWidgets). Third-party reactors can plug into Twisted, and provide support for additional event loops.

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.

Multiple services fork of original multi-platform inadyn, and inadyn-advanced projects. Supports many update services, easily extendable for others including additional servers config file, custom response codes, custom parameter names, and custom update server type.

KeexyBox allows you to do parental control, block ads, limit telemetry, and browse the Internet anonymously from your home network without installing any software on your devices. It also can be used to create a public wireless access point with the captive portal. It is a software program which requires a Raspberry PI box and which is installed on Raspbian. It constitutes a cut-off point between your devices (computers, tablets, smartphones, etc.) and your router or Internet box. KeexyBox acts as a default gateway and DNS server for the devices in your home network. It thus intercepts all connections to the Internet to carry out website filtering or to activate browsing via the Tor anonymity network according to connection profiles which you have configured.
