## 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.

## Enable support for HTTP/3 (HTTP over QUIC)
## Note that, like DNSCrypt but unlike other HTTP versions, this uses
## UDP and (usually) port 443 instead of TCP.

http3 = false

## When http3 is true, always try HTTP/3 first for DoH servers.
## If the HTTP/3 connection fails, fallback to HTTP/2 and don't try
## HTTP/3 again for that server. By default, HTTP/3 is only used for
## servers that advertise support via the Alt-Svc header.
##
## WARNING: This setting is disabled by default because it will make
## connections significantly slower for servers that don't support HTTP/3.
## This is primarily a workaround for server operators who haven't
## configured their servers to send proper Alt-Svc headers. The better
## solution is to reach out to these operators and encourage them to
## fix their servers to correctly advertise HTTP/3 support.

http3_probe = false


## SOCKS proxy
## Uncomment the following line to route all TCP connections to a local Tor node
## Tor doesn't support UDP, so set `force_tcp` to `true` as well. When passing
## a random username and password to Tor's socks5 connection, dnscrypt-proxy gets
## an isolated circuit so it will not share an exit node with other applications.
## Note: the random username and password used by dnscrypt-proxy should not
## actually be defined in Tor's configuration.

## How long a DNS query will wait for a response, in milliseconds.
## If you have a network with *a lot* of latency, you may need to

## Response for blocked queries. Options are `refused`, `hinfo` (default) or
## an IP response. To give an IP response, use the format `a:<IPv4>,aaaa:<IPv6>`.

###############################################################################

## Load-balancing strategy: 'wp2' (default), 'p2', 'ph', 'p<n>', 'first', or 'random'
## 'wp2' (default): Weighted Power of Two - selects the better performing server
## from two random candidates based on real-time RTT and success rates.
## 'p2': Randomly choose 1 of the fastest 2 servers by latency.
## 'ph': Randomly choose from fastest half of servers.
## 'p<n>': Randomly choose from fastest n servers (e.g., 'p3' for fastest 3).
## 'first': Always use the fastest server.
## 'random': Randomly choose from all servers.
## The response quality still depends on the server itself.

# lb_strategy = 'wp2'

## Set to `true` to constantly try to estimate the latency of all the resolvers
## and adjust the load-balancing parameters accordingly, or to `false` to disable.
## Default is `true`, which makes the `wp2` `lb_strategy` work well.

# lb_estimator = true

## Dynamically reduce query timeout as the number of concurrent connections
## approaches max_clients to prevent overload. Value must be between 0.0 and 1.0.
## 0.0 = no reduction, 1.0 = maximum reduction.
## Uses a quartic curve to keep timeout high at low load and reduce sharply near limit.
## For example, with timeout=5000ms, max_clients=250, and timeout_load_reduction=0.75:
## - At 125 connections (50% load): timeout remains ~4765ms (95.3%)
## - At 187 connections (75% load): timeout reduces to ~3826ms (76.5%)
## - At 225 connections (90% load): timeout reduces to ~2539ms (50.8%)
## - At 250 connections (100% load): timeout reduces to ~1250ms (25%)
## This helps maintain responsiveness under high load by failing fast.

# timeout_load_reduction = 0.75

## Bootstrap resolvers
##
## These are normal, non-encrypted DNS resolvers, that will be only used
## for one-shot queries when retrieving the initial resolvers list and if
## the system DNS configuration doesn't work.
##
## No user queries will ever be leaked through these resolvers, and they will
## not be used after IP addresses of DoH resolvers have been found (if you are
## using DoH).
##
## They will never be used if lists have already been cached, and if the stamps
## of the configured servers already include IP addresses (which is the case for
## most of DoH servers, and for all DNSCrypt servers and relays).
##
## They will not be used if the configured system DNS works, or after the
## proxy already has at least one usable secure resolver.
##
## Resolvers supporting DNSSEC are recommended, and, if you are using
## DoH, bootstrap resolvers should ideally be operated by a different entity
## than the DoH servers you will be using, especially if you have IPv6 enabled.
##
## People in China may want to use 114.114.114.114:53 here.
## Other popular options include 8.8.8.8, 9.9.9.9 and 1.1.1.1.
##
## If more than one resolver is specified, they will be tried in sequence.
##
## TL;DR: put valid standard resolver addresses here. Your actual queries will
## not be sent there. If you're using DNSCrypt or Anonymized DNS and your
## lists are up to date, these resolvers will not even be used.

bootstrap_resolvers = ['9.9.9.11:53', '8.8.8.8:53']

## the resolvers list:

##   running with active servers (*)
## - or else, queries will be sent to fallback servers
## - finally, if `ignore_system_dns` is `false`, queries will be sent
##   to the system DNS
##
## (*) this is incompatible with systemd sockets.
## `listen_addresses` must not be empty.

## if the network is up. It can be any address and any port, even if

[anonymized_dns]

## Routes are indirect ways to reach DNSCrypt servers.
##
## A route maps a server name ("server_name") to one or more relays that will be
## used to connect to that server.
##
## A relay can be specified as a DNS Stamp (either a relay stamp, or a
## DNSCrypt stamp) or a server name.
##
## The following example routes "example-server-1" via `anon-example-1` or `anon-example-2`,
## and "example-server-2" via the relay whose relay DNS stamp is
## "sdns://gRIxMzcuNzQuMjIzLjIzNDo0NDM".
##
## !!! THESE ARE JUST EXAMPLES !!!
##
## Review the list of available relays from the "relays.md" file, and, for each
## server you want to use, define the relays you want connections to go through.
##
## Carefully choose relays and servers so that they are run by different entities.
##
## "server_name" can also be set to "*" to define a default route, for all servers:
## { server_name='*', via=['anon-example-1', 'anon-example-2'] }
##
## If a route is ["*"], the proxy automatically picks a relay on a distinct network.
## { server_name='*', via=['*'] } is also an option, but is likely to be suboptimal.
##
## Manual selection is always recommended over automatic selection, so that you can
## select (relay,server) pairs that work well and fit your own criteria (close by or
## in different countries, operated by different entities, on distinct ISPs...)

# routes = [
#    { server_name='example-server-1', via=['anon-example-1', 'anon-example-2'] },

[dns64]

## DNS64 is a mechanism for synthesizing AAAA records from A records.
## It is used with an IPv6/IPv4 translator to enable client-server
## communication between an IPv6-only client and an IPv4-only server,
## without requiring any changes to either the IPv6 or the IPv4 node,
## for the class of applications that work through NATs.
##
## There are two options to synthesize such records:
## Option 1: Using a set of static IPv6 prefixes;
## Option 2: By discovering the IPv6 prefix from DNS64-enabled resolver.
##
## If both options are configured - only static prefixes are used.
## (Ref. RFC6147, RFC6052, RFC7050)
##
## Do not enable unless you know what DNS64 is and why you need it, or else
## you won't be able to connect to anything at all.

## Static prefix(es) as Pref64::/n CIDRs

# prefix = ['64:ff9b::/96']

## DNS64-enabled resolver(s) to discover Pref64::/n CIDRs
## These resolvers are used to query for Well-Known IPv4-only Name (WKN) "ipv4only.arpa." to discover only.
## Set with your ISP's resolvers in case of custom prefixes (other than Well-Known Prefix 64:ff9b::/96).
## IMPORTANT: Default resolvers listed below support Well-Known Prefix 64:ff9b::/96 only.

# resolver = ['[2606:4700:4700::64]:53', '[2001:4860:4860::64]:53']

## Encrypt client IP addresses in plugin logs using IPCrypt
## This provides privacy for client IP addresses while maintaining
## the ability to distinguish between different clients in logs

## Encryption algorithm (default: "none")
## - "none": No encryption (default)
## - "ipcrypt-deterministic": Deterministic encryption (same IP always encrypts to same value) - requires 16-byte key
## - "ipcrypt-nd": Non-deterministic encryption with 8-byte tweak - requires 16-byte key
## - "ipcrypt-ndx": Non-deterministic encryption with 16-byte tweak (extended) - requires 32-byte key
## - "ipcrypt-pfx": Prefix-preserving encryption (preserves network prefix relationships) - requires 32-byte key

algorithm = "none"

## Encryption key in hexadecimal format (required if algorithm is not "none")
## Key size depends on algorithm:
## - ipcrypt-deterministic: 32 hex chars (16 bytes) - Generate with: openssl rand -hex 16
## - ipcrypt-nd: 32 hex chars (16 bytes) - Generate with: openssl rand -hex 16
## - ipcrypt-ndx: 64 hex chars (32 bytes) - Generate with: openssl rand -hex 32
## - ipcrypt-pfx: 64 hex chars (32 bytes) - Generate with: openssl rand -hex 32
## Example for deterministic/nd: key = "1234567890abcdef1234567890abcdef"
## Example for ndx: key = "1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
