Why is My MAC-Address Resolved Backwards My IP-Address

Copper Contributor

When I go into my monitoring software, new and strange MAC addresses keep popping up. These MAC addresses also have an associated IP address and when I then convert my MAC address to decimal I get the IP address written backwards.

 

Example:
MAC--> 49-CA-B7-0A-00-00
IP --> 10.183.202.73

 

The DHCP recognizes this address also as BAD_ADDRESS and my question is now, can it be because of the DHCP, DNS or the monitoring software OpUtils?

And if you have a solution, can you explain me how I can work around this so that it no longer occurs?
