Does anyone know what this means because I'm stumped and can't find anything in the hosting package that mentions IP addresses or A Records!

I have done this the other way around. I used the DNS management option on 1&1 to point to another host's name servers that contained the IP of the website. But I was able to add the domain in the control panel of the other host (without transferring the domain to them) - whereas on 1&1 this wasn't possible.
This is what is required to get browsers to see the correct server.
As far as Apache knowing which website is which in a shared environment, that is up to the hosting company to establish handling. They do not need to control the domain registration or the DNS service in order to do that.
