## List of servers to use
##
## Servers from the "public-resolvers" source (see down below) can
## be viewed here: https://dnscrypt.info/public-servers
##
## If this line is commented, all registered servers matching the require_* filters
## will be used.
##
## Require servers (from static + remote sources) to satisfy specific properties
# Use servers reachable over IPv4
ipv4_servers = true
# Use servers reachable over IPv6 -- Do not enable if you don't have IPv6 connectivity
ipv6_servers = false
# Use servers implementing the DNSCrypt protocol
dnscrypt_servers = true
# Use servers implementing the DNS-over-HTTPS protocol
doh_servers = true
## Require servers defined by remote sources to satisfy specific properties
# Server must support DNS security extensions (DNSSEC)
require_dnssec = true
# Server must not log user queries (declarative)
require_nolog = true
# Server must not enforce its own blacklist (for parental control, ads blocking...)
require_nofilter = true
# Server names to avoid even if they match all criteria
disabled_server_names = []
## Always use TCP to connect to upstream servers.
## This can be useful if you need to route everything through Tor.
## Otherwise, leave this to `false`, as it doesn't improve security
## (dnscrypt-proxy will always encrypt everything even using UDP), and can
## only increase latency.
force_tcp = false
## Use the REFUSED return code for blocked responses
## Setting this to `false` means that some responses will be lies.
## Unfortunately, `false` appears to be required for Android 8+
refused_code_in_responses = false
## Load-balancing strategy: 'p2' (default), 'ph', 'fastest' or 'random'
# lb_strategy = 'p2'
## Log level (0-6, default: 2 - 0 is very verbose, 6 only contains fatal errors)
log_level = 6
## Delay, in minutes, after which certificates are reloaded
cert_refresh_delay = 240
## DNSCrypt: Create a new, unique key for every single DNS query
## This may improve privacy but can also have a significant impact on CPU usage
## Only enable if you don't have a lot of network load
# dnscrypt_ephemeral_keys = false
## DoH: Disable TLS session tickets - increases privacy but also latency
# tls_disable_session_tickets = false
## DoH: Use a specific cipher suite instead of the server preference
## 49199 = TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

## Fallback resolver
## This is a normal, non-encrypted DNS resolver, that will be only used
## for one-shot queries when retrieving the initial resolvers list, and
## only if the system DNS configuration doesn't work.
## No user application queries will ever be leaked through this resolver,
## and it will not be used after IP addresses of resolvers URLs have been found.
## It will never be used if lists have already been cached, and if stamps
## don't include host names without IP addresses.
## It will not be used if the configured system DNS works.
## A resolver supporting DNSSEC is recommended. This may become mandatory.
##
## People in China may need to use 114.114.114.114:53 here.
## Other popular options include 8.8.8.8 and 1.1.1.1.
fallback_resolver = '1.1.1.1:53'
## Never let dnscrypt-proxy try to use the system DNS settings;
## unconditionally use the fallback resolver.

## The proxy will remain fully functional to respond to queries that
## plugins can handle directly (forwarding, cloaking, ...)

## Immediately respond to IPv6-related queries with an empty response
## This makes things faster when there is no IPv6 connectivity, but can
## also cause reliability issues with some stub resolvers.
## Do not enable if you added a validating resolver such as dnsmasq in front
## of the proxy.

#        Servers        #
#########################
## Remote lists of available servers
## Multiple sources can be used simultaneously, but every source
## requires a dedicated cache file.
##
## Refer to the documentation for URLs of public sources.
##
## A prefix can be prepended to server names in order to
## avoid collisions if different sources share the same for
## different servers. In that case, names listed in `server_names`
## must include the prefixes.
##
## If the `urls` property is missing, cache files and valid signatures
## must be already present; This doesn't prevent these cache files from
## expiring after `refresh_delay` hours.
