Nope. According to your example, you have defined two networks:

10.0.{0,1}.255 would be the broadcast address for each one
10.0.{0,1}.0 would <still> be the network address itself - not a host address

There's only one valid application/use of .0 as a host address - check http://www.ietf.org/rfc/rfc3021.txt?number=3021 
- which also includes a lot if interesting pointers to other RFCs and addressing rules for IPv4.

Considering the answers Hannibal got, I tend to think the packet to .0 got translated by a route connected to that 
network to an L2 broadcast - and more than one host received it and replied to it. So actually those open ports could 
come from one, two, or three different hosts.
