Hey guys,
Any further hints on this would be very appreciated.
Thanks and all the best.

That is the primary goal of that configuration, so, It sets the domain in both the directory, the global default domain variable and the name of the internal profile to be identical to the ip on the box that can reach the internet. Then it sets the sip to force everything to that value. When you want to detach from this behavior, you are probably on a venture to do some kind of multi-home setup.

When you define aliases to match all of the possible domains hosted on a particular profile, then when you try to take a user at host.com notation and decide which profile it came from, you can use the aliases to find it providing you have added <alias name="host.com"/> to that profile.

The default directory uses global config vars to set the domain to match the local ip on the box. So now you will have a domain in your config that is your ip, and the internal profile will attach to it and add an alias so that value expands to match it.
