Which Plugin Does What I Need?

I want to setup a multisite installation with both multiple domains (dom1.com dom2.com dom1.net etc) and subdomains (site1.dom1.com bobssite.dom2.com etc) and wondering which plugin or plugins would be best to use?

Sorry for the question as I am slightly confused with the multiple options available.

Thank you for your time, knowledge and support.
