+  #### RESERVED IP RANGE EXCEPTIONS ######
+  ########################################
+  #
+  # Explicitly allow or block outgoing dialing within the provided IPv4/v6 CIDR ranges.
+  #
+  # By default, as a basic security precaution, GoToSocial blocks outgoing dialing within most "special-purpose"
+  # IP ranges. However, it may be desirable for admins with more exotic setups (proxies, funky NAT, etc) to
+  # explicitly override one or more of these otherwise blocked ranges.
+  #
+  # Each of the below allow/block config options accepts an array of IPv4 and/or IPv6 CIDR strings.
+  # For example, to override the hardcoded block of IPv4 and IPv6 dialing to localhost, set:
+  #
+  #   allow-ips: ["127.0.0.1/32", "::1/128"].
+  #
+  # You can also use YAML multi-line arrays to define these, but be diligent with indentation.
+  #
+  # When dialing, GoToSocial will first check if the destination falls within explicitly allowed IP ranges,
+  # then explicitly blocked IP ranges, then the default (hardcoded) blocked IP ranges, returning OK on the
+  # first allowed match, not OK on the first blocked match, or just defaulting to OK if nothing is matched.
+  #
+  # As with all security settings, it is better to start too restrictive and then ease off depending on
+  # your use case, than to start too permissive and try to close the stable door after the horse has
+  # already bolted. With this in mind:
+  # - Don't touch these settings unless you have a good reason to, and only if you know what you're doing.
+  # - When adding explicitly allowed exceptions, use the narrowest possible CIDR for your use case.
+  #
+  # For reserved / special ranges, see:
+  # - https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml
+  # - https://www.iana.org/assignments/iana-ipv6-special-registry/iana-ipv6-special-registry.xhtml
