Ddclient is a Perl client used to update dynamic DNS entries for accounts on 'Dynamic DNS Network Services' free DNS service. It currently supports a lot of different routers and a few different services. The project moved to github. See https://www.github.com/ddclient/ddclient for support.

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.

dnswalk is a DNS debugger. It performs zone transfers of specified domains, and checks the database in numerous ways for internal consistency, as well as accuracy.

A DNS server for Unix and Windows platforms, supporting authoritative service (master/slave) as well as caching. Also featuring a graphical master file editor (mfedit), a graphical DNS query tool (dnsquery) and a DNS programming library for C++ (poslib).

Dynamic DNS update tool for DynDns services. Features: Stateful memory, a complete activity log, configuration file, and cross-platform portability.

IP change detection script for UNIX systems. Can be used to map static domain to dynamic IP. Works behind NAT. Uses HTTP browser or network interface to get public IP. To be used with task scheduler (Cron or like, sample crontab file shipped).

gh-tool is a command-line interface to gethostby*, in libresolv/libc. It allows one to check the local system's notion of an IP->DNS or DNS->IP mapping, including aliases, directly, rather than digging for mappings in DNS, which may not pertain.

CrossIP is a dns update client for console and gui environments using the open source ThatIP-J library.
