 ### Approved host : IP combinations
 
-Hosts are considered billable if the Defender EASM system has observed resolutions within the last 30 days. If the host is in the Approved Inventory state, the host : IP combination will be identified as a billable asset. All hosts in the Approved Inventory state are considered billable, regardless of the state of the coinciding IP address. The IP address does not need to be in the Approved Inventory state for the host : IP combination to be included in your billable asset count.

-The list is then analyzed to identify duplicate entries and eliminate duplicate hosts.  If a host is a subdomain of a parent host that resolves to the same IP address, we'll exclude the child from the billable host count. For example, if both www.contoso.com and contoso.com resolve to 1.2.3.4, then we'll exclude www.contoso.com/ 1.2.3.4 from our Host Count list.
