Does 192 share the first two bits with 128-191?

If not, then it will not be permitted by your prefix list!

Hello,
   
  I need to permit only class B addresses (128.0.0.0 - 191.255.255.255)
using prefix list. I used
   
  ip prefix-list <name> permit 128.0.0.0/2 ge 16 le 24
   
  Will the above command will stop permitting for example 192.0.0.5/24
   
  If it is so could someone explain how that works.
   
  Thanks,
  Vignesh
