Thanks For your Reply,
Hi Kdyer and Sealeopard
I tried many variation but still doesn't work.
Do you have a sample working Code for IsinSubnet.UDF and IsInIprange.UDF

here's the result of my Kixstrip420 code:

Kixstrip 4.20 (vs 4.00e) 0.49 (sec)

input 80 iptest3.kix
output 80 test.out (skip: 0 blocks: 0 labels: 1)
block_check block_structures=17 functions=3 labels=1
tab=6 (default)

And Test.out
