{% if blocky_conditional_mapping is defined %}

# 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 `fallbackUpstream` was set to `true`, 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.

# 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

# optional: configuration for caching of DNS responses
caching:
  # duration how long a response must be cached (min value).
  # If <=0, use response's TTL, if >0 use this value, if TTL is smaller
  # Default: 0
  minTime: 0
  # duration how long a response must be cached (max value).
  # If <0, do not cache responses
  # If 0, use TTL
  # If > 0, use this value, if TTL is greater
  # Default: 0
  maxTime: 0
  # Max number of cache entries (responses) to be kept in cache (soft limit). Useful on systems with limited amount of RAM.
  # Default (0): unlimited
  maxItemsCount: 0
  # if true, will preload DNS results for often used queries (default: names queried more than 5 times in a 2-hour time window)
  # this improves the response time for often used queries, but significantly increases external traffic
  # default: false
  prefetching: true
  # prefetch track time window (in duration format)
  # default: 120
  prefetchExpires: 120
  # name queries threshold for prefetch

  # Max number of domains to be kept in cache for prefetching (soft limit). Useful on systems with limited amount of RAM.
  # Default (0): unlimited

  # Time how long negative results (NXDOMAIN response or empty result) are cached. A value of -1 will disable caching for negative results.
  # Default: 30m
  cacheTimeNegative: -1

# optional: configuration of client name resolution
clientLookup:
  # optional: this DNS resolver will be used to perform reverse DNS lookup (typically local router)
  upstream: {{ blocky_local_upstream | default ("192.168.2.1") }}
  # optional: some routers return multiple names for client (host name and user defined name). Define which single name should be used.
  # Example: take second name if present, if not take first name
  # singleNameOrder:
  #   - 2
  #   - 1


# optional: configuration for prometheus metrics endpoint
prometheus:
  # enabled if true
  enable: {{ blocky_prometheus | default ("false") }}

# optional: Mininal TLS version that the DoH and DoT server will use
# minTlsServeVersion: 1.3

# if https port > 0: path to cert and key file for SSL encryption. if not set, self-signed certificate will be generated

#keyFile: server.key

# optional: use these DNS servers to resolve blacklist urls and upstream DNS servers. It is useful if no system DNS resolver is configured, and/or to encrypt the bootstrap queries.

  - tcp+udp:9.9.9.9

# optional: drop all queries with following query types. Default: empty

  # tls: 853
  # optional: Port(s) and optional bind ip address(es) to serve HTTPS used for prometheus metrics, pprof, REST API, DoH... If you wish to specify a specific IP, you can do so such as 192.168.0.1:443. Example: 443, :443, 127.0.0.1:443,[::1]:443
  # https: 443
  # optional: Port(s) and optional bind ip address(es) to serve HTTP used for prometheus metrics, pprof, REST API, DoH... If you wish to specify a specific IP, you can do so such as 192.168.0.1:4000. Example: 4000, :4000, 127.0.0.1:4000,[::1]:4000
