## Server ##

# The domain name of the server, with optional explicit port.
# This is used by remote servers to connect to this server,
# e.g. matrix.org, localhost:8080, etc.
# This is also the last part of your UserID.
#
server_name: '${BASE_DOMAIN}'

# The public-facing base URL that clients use to access this HS
# (not including _matrix/...). This is the same URL a user would
# enter into the 'custom HS URL' field on their client. If you
# use synapse with a reverse proxy, this should be the URL to reach
# synapse via the proxy.

# Prevent federation requests from being sent to the following
# blacklist IP address CIDR ranges. If this option is not specified, or
# specified with an empty list, no ip range blacklist will be enforced.
#
# As of Synapse v1.4.0 this option also affects any outbound requests to identity
# servers provided by user input.
#
# (0.0.0.0 and :: are always blacklisted, whether or not they are explicitly
# listed here, since they correspond to unroutable addresses.)
