You should not put the IP address in httpd.conf (unless you're using the
old-style IP-address based virtual domains, with multiple IP addresses,
which is unlikely).  Instead, put the fully qualified domain name (FQDN)
for the "ServerName" section of your httpd.conf. (Presumably this would
not change regularly.)

The ServerName (and ServerAlias) section(s) determine which virtual
configuration goes which which virtual domain, based on the "Host:"
header sent by the browser.  Note that this means every virtual host
will probably have "<VirtualHost *>" to open the virtual host container,
but will then contain an appropriate ServerName or ServerAlias.

You might also look at the graphical Apache configurator provided by Red
Hat in RHL 8.0 -- it should do virtual domains.  I can't recall what the
name of the binary is for this, sorry.
