subnetting IP address

I have been given a class C address range from my ISP. I want to subnet it. I want 7 DMZ’s which I can get by using 255.255.255.252 subnet mask on the 1st 6 and 255.255.255.248 on the 7th one. I want to split the rest of the IP’s into the range of x.x.x.32 thru x.x.x.127 and x.x.x.128 thru x.x.x.255. the .128 thru .255 I can get by using 255.255.255.128, will this also work for the x.x.x.32 – x.x.x.127 range as well? When I run this through a subnet calculator, it says that address ranges .1 thru .127 will be used. If I have a different subnet mask for .1 thru .31 will this be a problem?
