I have also noticed this in the past, but never been able to track it down. There must be some VM, network test utility, piece of hardware,… out there in the wild that takes a liking to this MAC address (probably intended to be some sort of broadcast address for some other non-IP protocol, but somehow ending up in a DHCP request)
When someone does find the culprit on their network we would all love to hear about it!

This has come up once before here:

For now blocked the access to the internet and from the internet to this address

People can clone MACs and set their mac address to anything they like, so if you are running wireless, that could be the case here.  Just a possibility.
