We control IP (Internet Protocol) addresses XXX.YYY.224.0 through XXX.YYY.239.255 and as I mentioned [1], not all the addresses in that range follow the same path from my home computer to the office. I was curious so I decided to map the paths:
[The various paths of a /20 routing block] [2]
This image shows the overall paths, with the double circles the termination points of the various IPs and as far as I can tell, it looks like the “/20” we have is being routed as 16 individual “/24” networks (aka (also known as) “Class-C”) through out different providers (some through one, some through the other).
Curiouser and curiouser …

I think if you check with Dan, we are routing various IP's with preferences for different carriers in order to have our actual bandwidth usage line up with our financial commitments to our carriers.
Perhaps that may solve the mystery?
Perhaps.
