With "no ip routing" you'd normally have "ip default-gateway" in the
configuration, but I assume that's not the case here. Even with a
correct netmask I've seen examples of a switch learning ARP entries for
"foreign" hosts. Try "show ip arp" on the device. You should be able to
configure all routers on the subnet with "no ip proxy-arp", a best
practice IMO.
