Sounds like you want to use a prefix list.
Ip prefix test sequence 5 permit 145.0.0.0/8 ge 16 le 16
At least I think that's right... Basically it says match the first 8
bits (e.g. 145) and any subnet that is /16

Mmmm
145.0.0.0 /8 will match anything above /8 subnet.. like /9, /10, /11 etc
I want to match only 145.x.0.0/16... Ex 145.1.0.0/16, 145.2.0.0/16 etc
But not 145.0.0.0/8...
It should be /16 for sure...
