Answer 1

Please see the below link https://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spsite.hostname(v=office.12).aspx

You can use SPContext.Current.Site.HostName to get the host name.

Answer 2

The following code should provide the details you need, depending on if you want the root site, or site collection URL, or host name.

// Root Site – eg. Web App URL
var rootSiteCollectionURL = SPContext.Current.Web.Site.WebApplication.Sites[0].Url;

// Site Collection URL
var SiteCollectionURL = SPContext.Current.Web.Site.Url;

// Host Name of current Site Collection (Machine Name)
var HostName - SPContext.Current.Site.HostName
