For laughs I tried to use the highest and lowest address of a class B 
network as loopback addresses. Some stuff will not work if you choose the 
highest or lowest address of a classful network, in your case class C.

Either you start logging cases against this so they fix the code, or if 
you value your time, don't use these addresses (.0.0 and .255.255 on 
128.0.0.0-191.255.255.255 and .0 and .255 of 192.0.0.0-223.255.255.255).

I would imagine the same problem exists with .0.0.0 and .255.255.255 in 
class A space.
