Correlation of usage to corresponding users through device and DNS agents

A system for tracking usage of a plurality of hosted software applications by user devices having private and public Internet Protocol (IP) addresses comprising:

• a software which is executed on a first computing device which associates a private IP address of a device with a user identifier and records a user session in a first database, the user session associating the user identifier with the private IP address and the user session further related to a user accessing a hosted software application;
• a Domain Name System (DNS) server which matches the private IP address to a log record to generate matched data having a time stamp, a domain and the private IP address associated therewith;
• and
• a second computing device which correlates the matched data to the user session to associate the user identifier with the time stamp, domain and private IP address.

A system for tracking usage of a plurality of hosted software applications by user devices having a private Internet Protocol (IP) address and associated with a public IP address comprising:

• a portal provided by software which is executes on a first computer which associates a private IP address of a computing device with a user identifier and records a user session in a first database, the user session associating the user identifier with the private IP address and the user session further related to a user accessing a hosted software application via a network;
• the computing device further associated with a public IP address;
• a Domain Name System (DNS) server associated with the network, the DNS server matches the private IP address to a log record to generate matched data indicating a time stamp, a domain and the private IP address;
• and
• a second computing device which correlates the matched data to the user session to associate the user identifier with the time stamp, domain and private IP address.

A method of tracking usage of a plurality of hosted software applications comprising:

• receiving data from a tracking software executing on a processor, the data indicative of a private Internet Protocol (IP) address of one of a plurality of devices which accesses one or more of the plurality of hosted software applications via a network, the one of the plurality of devices further associated with a public IP address;
• determining at a server a user identifier based on said data to generate second data which associates the user identifier with said private IP address;
• tracking usage of said software application with a Domain Name System (DNS) server to associate the private IP address of the device with a log record;
• and
• matching said log record with the user identifier by the private IP address.
