Nope. MAC address always starts with 00:16:A4 DHCP hostname always starts with UA followed by a long number
This forum post leads me to believe it is vehicle or RR car tracking: http://forum.mikrotik.com/viewtopic.php?t=76847 From: Josh Luthman Sent: Tuesday, June 16, 2015 3:37 PM To: [email protected] Subject: Re: [AFMUG] vehicle tracking systems and open WiFi hotspot Do the DHCP lease names say Truck-PC?

The WiFi signal is always low, around -90. Doing some research on the web, I think this may be due to vehicle tracking systems, I'm not sure if these are vehicles in the parking lot or whizzing by on the tollroad. Also not sure if they are from the vehicle or the intermodal container it is carrying. I'm not sure it is a big problem, we have the DHCP lease time set to 30 minutes. Has anyone else run into this, and if so, did you take any action? I guess we could block connections from those MAC addresses, or maybe set a higher signal threshold to connect. Or maybe we should just let them check their location or call the mothership or whatever they do. BTW, don't say this is a DOS attack trying to exhaust the DHCP leases, they dribble in 1 or at most 2 at a time. If we had the DHCP leases set to 30 days, it could be a problem unless we expanded the pool.
