Technitium DNS Server is een opensource DNS server met uitgebreide mogelijkheden, die kan worden gebruikt om ad- en malware buiten de deur te houden en je privacy te beschermen. Het is daarmee vergelijkbaar met Pi-hole en AdGuard Home. De software is beschikbaar voor Windows, Linux, macOS en Docker en is eenvoudig op te zetten en in gebruik. Kort geleden is versie 14.0 uitgekomen en inmiddels is er ook alweer een update verschenen die enkele kleine problemen moet verhelpen.
