Weird multicast address right in the middle of my scope

So I have a issue where my wireless controller is not responding properly. I have an 8.0 subnet on a /23. When I try to ping 9.36 from anything on the 8 it does not respond. If I try to ping 9.36 from anything on the 9 then it responds fine. Here is where it gets odd. Arp is showing a multicast address on 9.36. 00:00:5E:00:01:01. Computers with a 9 address show the same arp entry. What is this multicast address?
