10.x.x.x networks

I've been having a friendly arguement with some friends at work about wheather it's right or wrong to use 10.255.255.0/24 for a network. Technically it should work, but during our conversations we keep coming back to best practiced IP schemes. I'm wondering what others think about this. Is using 10.255.255.0/24 and possibly the reverse 10.0.0.0/24 bad practice? Mike
