File apache2-listen.conf of Package apache2.35278
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports. See also the <VirtualHost> directive.
#
# https://httpd.apache.org/docs/2.4/mod/mpm_common.html#listen
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
# When we also provide SSL we have to listen to the
# standard HTTP port (see above) and to the HTTPS port
#
# Note: Configurations that use IPv6 but not IPv4-mapped addresses need two
# Listen directives: "Listen [::]:443" and "Listen 0.0.0.0:443"
#
#Listen 12.34.56.78:80
#Listen 80
#Listen 443
