== DNSdist ==
PowerDNS DNSdist ('''dnsdist'''<ref>{{cite web|url=https://dnsdist.org/ |title=PowerDNS DNSdist |publisher=dnsdist.org |date= |accessdate=2023-05-11}}</ref>) is a caching DNS proxy, with many features including:

* Load Balancing of DNS Queries
* DNS Encryption Support - DNS over HTTPS, DNS over TLS, both upstream and downstream (i.e. to clients and backends)
* Lua Policy Engine - Extensive capabilities for creating rules for processing DNS packets, such as changing the response, re-routing a query or blocking traffic over a max QPS from a subnet.
* Dynamic Rule Generation - Used to create Dynamic Blocks which are short-lived rules, automatically inserted based on configurable thresholds and the analysis of recently received traffic. Used to deal with DoS attacks

DNSdist is available as a standalone package, and can be deployed with PowerDNS Authoritative Server or Recursor, or any other third-party DNS server.
