NextDNS

NextDNS functions as a DNS‑level firewall that filters traffic for all devices and networks. It blocks security threats such as malware, phishing, cryptojacking and other malicious activity by consulting real‑time threat‑intelligence feeds and by analyzing DNS queries and responses on the fly. Users can enable a range of protection types and rely on constantly updated lists of dangerous domains.

The service also provides privacy controls, removing ads and trackers across websites and applications. It incorporates popular blocklists and native tracking protection that can intercept trackers operating at the operating‑system level, as well as mechanisms to block third‑party trackers that masquerade as first‑party.

Parental‑control features let families restrict access to content deemed inappropriate, enforce SafeSearch and YouTube Restricted Mode, and schedule allowed usage for specific apps or websites. Detailed analytics and configurable logging give insight into traffic patterns, with options for log retention duration and storage location to meet data‑residency preferences.
