Take for example, pcrepairnorthshore.com. Imagine pcrepairnorthshore.com is divided into two zones. The first zone hosts www.pcrepairnorthshore.com and ftp.pcrepairnorthshore.com. Let’s pretend we have a site called offsite.pcrepairnorthshore.com.
We delegate it to a new zone that hosts the offsite.pcrepairnorthshore.com
and its subdomains ftp.offsite.pcrepairnorthshore.com
and www.offsite.pcrepairnorthshore.com.
