1. A method to correct data source error, comprising:

  • identifying, by executing an instruction with a processor, a first hostname label based on a reverse resolve of an Internet protocol (IP) address corresponding to a household;

    parsing the first hostname label to identify a service provider name;

    invoking a trace route of the IP address corresponding to the household, the trace route originating from two or more originating IP addresses to identify second and third hostname labels associated with corresponding router last hops, the two or more originating IP addresses different from each other and targeting the same IP address corresponding to the household;

    when the second and third hostname labels include a matching location indicator, confirming the service provider name is valid; and

    when the first hostname label service provider name matches a service provider name in self reported data, correcting, by executing an instruction with the processor, an error metric of a data source storing the self reported data by adjusting a weight value associated with the self reported data.
