  Description     : DNS-over-HTTPS proxy client for NextDNS and other DoH providers

 NextDNS CLI is a daemon that acts as a local DNS proxy, receiving standard
 DNS queries from the system and forwarding them encrypted over HTTPS
 (DNS-over-HTTPS, DoH) to NextDNS servers or any other DoH provider.
 .
 It is primarily aimed at routers and UNIX-based systems where a lightweight,
 fully open-source DoH client is preferred over GUI-based solutions.
 .
 Typical use cases include:
  - Workstations and laptops that need encrypted DNS with filtering and
    logging capabilities via a NextDNS profile;
  - Home and small office routers serving DNS for the entire local network,
    associating queries to individual devices by name;
  - Embedded and IoT systems running OpenWrt, DD-WRT, Merlin, EdgeOS, and
    other router firmware.
 .
 Main features:
  - Transparent DNS proxy: listens on standard port 53 (UDP and TCP) and
    requires no changes to existing applications;
  - DNS-over-HTTPS using HTTP/2, with TLS 1.3 and automatic selection of
    the lowest-latency server endpoint;
  - Local DNS cache to reduce latency and the number of upstream queries;
  - Split-horizon DNS: forwards specific domains to designated resolvers
    while sending the rest to NextDNS;
  - Router mode: listens on all interfaces and serves the entire local
    network, with per-device query attribution via ARP, NDP, mDNS and
    DHCP discovery;
  - Automatic fallback to plain DNS during startup and captive portal
    detection, ensuring connectivity is never broken;
  - Compatible with any DoH provider; advanced filtering and analytics
    features require a NextDNS account (https://nextdns.io).
