How do I find the IP address for a Gateway?

This article will show how to find the IP address assigned to a gateway when Internet access is through a customer’s network.

Although there are various methods to find a gateway’s IP address, we are going to explore the 2 most common.

• Local router DHCP List
  • Within the router’s DHCP list look for the IP address assigned to the gateway’s Mac Address, which is as follows:
    00:1C:2C:GATEWAY_MAC_ADDRESS
    • GATEWAY_MAC_ADDRESS: last 6 hexadecimal characters with which the gateway has been registered onto the OPIBLUE account (as an example see the attached image)
      
• Using any of the networking tools (e.g., command line, Fing, etc..) list the active devices and search for the IP Address assigned to the gateway’s Mac address:
  00:1C:2C:GATEWAY_MAC_ADDRESS
