Tip Sheet: Hide report tips
Use this report to see the DNS names of visitors to your web site, consolidated at two useful levels of domain name.
FlashStats defines a secondary domain name as the two or three right-most parts of a DNS name. For two-letter country code domains (ccTLDs), FlashStats uses the last three parts of the domain name. For all other top level domains, FlashStats uses the last two parts of the domain name.
This report is useful because it lets you see the DNS domain names of your visitors at a useful level of detail. For example, it will consolidate all AOL users into ".aol.com" rather than showing each separate AOL proxy.
See the Primary Domains report to see the visitor DNS names consolidated at one level of domain name, or the Visitor DNS Names report to see the fully qualified DNS name for each visitor.
You can perform a WHOIS lookup to get the registration information for any secondary DNS name. Just click on the name's "W" icon 
; the lookup results will appear in a new window.
If this report only shows one result (for "Unknown"), then FlashStats has not been configured to perform DNS lookups. In order to have FlashStats convert each IP address to its DNS name, click the All Advanced Options... button on the Report Set Options tab, and then make sure that the Perform DNS lookups check box is selected.
Please note that if you enable DNS lookups then FlashStats will convert all IP addresses during an extra step in its analysis. This will significantly increase the time required to generate a report, but only the first time each log file is analyzed. FlashStats will then cache the DNS names so that subsequent reports will not require any extra time. (By default, DNS names are cached for 60 days.)
Domain: The secondary domain name.
Hits: The total number of hits from the given secondary domain name. Each hit is counted separately, including duplicate hits from the same user (or domain).
Visits: The total number of visits from the given secondary domain name.
