Alternate access mappings enable SharePoint 2013 to map web requests to the correct web applications and sites, and they enable SharePoint 2013 to serve the correct content back to the user. Each web application can be associated with a collection of mappings between internal and public URLs.
How many alternate access mappings can I use?
Alternate access mappings allow you to expose a web application in as many as five different zones, with a different IIS website backing each zone. Some people mistakenly refer to this as having up to five different web applications sharing the same content databases. In reality, there is just one web application.
Can a host named site collection use alternate access mappings?
Host-named site collections can’t use alternate access mappings. Host-named site collections are automatically considered in the Default zone, and the URL of the request must not be changed between the user and the server. Multiple internal URLs can be associated with a single public URL.
How many mappings can a web application support?
Each web application supports five collections of mappings per URL. The five collections correspond to five zones (default, intranet, extranet, Internet, and custom). When the web application receives a request for an internal URL in a particular zone, links on the pages returned to the user have the public URL for that zone.
