Top Cities report reveals geographic locations of devices sending and receiving the most traffic for the selected interval. The initial report view is organized by city, but you can include columns such as country, geo coordinates, and more.

Geographic information can be useful when tracking the origins of network traffic. For example, if your company has a website, you can detect the locations of the persons and businesses that are visiting your website by viewing the report.

Understanding location data

Public IP addresses. For public IPs (such as IP addresses outside your firewall, LAN, or enterprise boundaries) by default Network Traffic Analysis uses the location data provided by regional internet registries (RIRs), which is built into WhatsUp Gold for the source and destination addresses. Typically, the location is a metropolitan area region, such as a town. You can also associate ranges of IP addresses with a location using the NTA IP Groups Library.

Private IP addresses. For IP addresses inside your firewall beginning with 10.x.x.x or 192.168.x.x, it is best practice to associate location information with an IP Group using the NTA IP Groups Library.

Understand column data

The default view of each report contains a grid with the following columns:

  • Location. Field composed of top combined Cities with, State, and Country identifiers included.
    • Bytes. Number of bytes transmitted. Use Report Settings

      to sort by packet or flow count, or bytes.
  • Bit Rate. Average bit rate, in bits per second (bps).
  • Flows. Flows received from the Flow Sources (switch or router NetFlow observation points) for the current city.
  • Byte Percentage. Percentage of the total traffic for the specific item in the report category for the selected date range.

To display Flow and Packet measurements, click a column heading ( ) for column selection list ( ). You can also include:

  • City. Top combined cities (both sender and receivers).
  • Subdivision. Subdivision for the current city.
  • Country. Country for the current city.
  • Latitude. Degrees latitude associated with the current city.
  • Longitude. Degrees longitude associated with the current city.
