We have SharePoint 2010 Foundation on a single server farm with anonymous access turned off. The main web application requires an Active Directory account login; the site is extended to allow FBA logins.
When I look at the root site's web analytics Top Visitors report for the site most of the entries are employees' accounts. However, a handful of them are IP addresses. I asked one of our IT people who said that they are dynamically assigned internal
addresses so it is impossible to know who the user is. Can anyone tell me why the IP address is stored in the report for some of the users instead of the users' user names?
