upstream:
# these external DNS resolvers will be used. Blocky picks 2 random resolvers from the list for each query
# format for resolver: [net:]host:[port][/path]. net could be empty (default, shortcut for tcp+udp), tcp+udp, tcp, udp, tcp-tls or https (DoH). If port is empty, default port will be used (53 for udp and tcp, 853 for tcp-tls, 443 for https (Doh))
# this configuration is mandatory, please define at least one external DNS resolver
default:
# example for tcp+udp IPv4 server (https://digitalcourage.de/)
#- 5.9.164.112
# Cloudflare
- 1.1.1.1
# example for DNS-over-TLS server (DoT)
#- tcp-tls:fdns1.dismail.de:853
# example for DNS-over-HTTPS (DoH)
#- https://dns.digitale-gesellschaft.ch/dns-query
# optional: use client name (with wildcard support: * - sequence of any characters, [0-9] - range)
# or single ip address / client subnet as CIDR notation
#laptop*:
#- 123.123.123.123
# optional: timeout to query the upstream resolver. Default: 2s
#upstreamTimeout: 2s
# optional: If true, blocky will fail to start unless at least one upstream server per group is reachable. Default: false
#startVerifyUpstream: true
# optional: Determines how blocky will create outgoing connections. This impacts both upstreams, and lists.
# accepted: dual, v4, v6
# default: dual
#connectIPVersion: dual
# optional: custom IP address(es) for domain name (with all sub-domains). Multiple addresses must be separated by a comma
# example: query "printer.lan" or "my.printer.lan" will return 192.168.178.3
#customDNS:
#customTTL: 1h
# optional: if true (default), return empty result for unmapped query types (for example TXT, MX or AAAA if only IPv4 address is defined).
# if false, queries with unmapped types will be forwarded to the upstream resolver
#filterUnmappedTypes: true
# optional: replace domain in the query with other domain before resolver lookup in the mapping
#rewrite:
#example.com: printer.lan
#mapping:
#printer.lan: 192.168.178.3,2001:0db8:85a3:08d3:1319:8a2e:0370:7344
# optional: definition, which DNS resolver(s) should be used for queries to the domain (with all sub-domains). Multiple resolvers must be separated by a comma
# Example: Query client.fritz.box will ask DNS server 192.168.178.1. This is necessary for local network, to resolve clients by host name
#conditional:
# optional: if false (default), return empty result if after rewrite, the mapped resolver returned an empty answer. If true, the original query will be sent to the upstream resolver
# Example: The query "blog.example.com" will be rewritten to "blog.fritz.box" and also redirected to the resolver at 192.168.178.1. If not found and if was set to , the original query "blog.example.com" will be sent upstream.
# Usage: One usecase when having split DNS for internal and external (internet facing) users, but not all subdomains are listed in the internal domain.
#fallbackUpstream: false
# optional: replace domain in the query with other domain before resolver lookup in the mapping
#rewrite:
#example.com: fritz.box
#mapping:
#fritz.box: 192.168.178.1
#lan.net: 192.168.178.1,192.168.178.2
# optional: use black and white lists to block queries (for example ads, trackers, adult pages etc.)

special:
- https://raw.githubusercontent.com/StevenBlack/hosts/master/alternates/fakenews/hosts
