How to build a lookup table based on a condition?

Hello all,

I can't figure out how to build a lookup with a condition. I have the following table which is my base search:

SubnetName     ip_address
Subnet_ABCD   10.177.99.53
Subnet_1234     10.8.183.3
Subnet_1234     10.8.182.233
Subnet_ABCD    10.177.83.244

And the following lookup table:

Last_SubnetName SubnetID    NetStart    NetEnd
Subnet_A    10.177.0.0/16   10.177.0.1  10.177.255.254
Subnet_B    10.8.0.0/16 10.8.0.1    10.8.255.254
Subnet_B    192.16.0.0/24   192.168.0.1 192.168.0.254

This is the closest I got after reading several articles, but as you can see, I got no luck. The result is simply blank every time I try it.

index=mybasesearch  ( [| inputlookup myLookupTable.csv | table Last_SubnetName,SubnetID,NetStart,NetEnd ]  AND last_ip_address
>=NetStart AND last_ip_address<=NetEnd)

Need your help to proceed.
