Do you mean netmasks like "255.128.255.0" ?  Those are a real 
abomination and probably not supported.. and I don't know of anything that 
would require them.

Or do you mean netmasks such as 1.1.1.1/19?  I don't know of any credible 
networking devices which wouldn't support them.  If so, please come out of 
the cave.
