IP subnetting task

hey guys

I need to create an ACL on my router to allow all networks under 44.102.0.0/16 except for two class-C networks 44.102.253.0/24 & 44.102.7.0/24

Can someone help me with the supernetting and VLSM with a minimum number of lines?

1) Please don't ask me why this cannot be done any other way - this is the only way possible for my networking scenario and device limitations
2) Don't worry about the actual ACL lines - just give me the networks and associated subnet masks (not wildcard masks)

thank you

access-list 10 deny ip 44.102.253.0 0.0.0.255
access-list 10 deny ip 44.102.7.0 0.0.0.255
access-list 10 allow ip 44.102.0.0 0.0.255.255

Could that work or do you actually have to use VLSM?

Wouldn't 44.102.8.0 255.255.128.0 encompass all hosts from 44.102.0.1 to 44.102.127.254?

Thanks
