title: How to manage Typo3 multisite domains?
body: <p>Two questions about Typo3 Multisite concept:</p>
  <p>1- Is it wise to keep main installation (I believe this is called “network” in Typo3 concept) on a kind of special domain which is not used for content like: “typo3panel.example.com” and have different domains for each different root pages (i.e. “site” in Typo3 concept)?</p>
  <p>2- How is different subdomains and domains managed in Typo3 multisite environment? Like for example I have added a root page (a site) and created the configuration for it with the entry point “business.com” and added another site for “brand.anotherbusiness.com”. Now how do I set this “business.com” and “brand.anotherbusiness.com” in terms of “network” to allow them to resolve to corresponding Typo3 site? For example how should I set the DNS records of those domains and what should I do more on Typo3 side? Because I can't seem to map the domains for the multisite environment and official docs do not cover it. I wonder if it's done through adding domain aliases?</p>
