    Help needed: match IP ranges / find number in between numbers

    Hi everyone,

    I am trying to find a way to go through a list of around 18'000 applications and identify in which of the 2'000 IP Sublets (ranges) they fit in. So far I thought of 2 options, but both go beyond my skills so help would be greatly appreciated. To make it easier the output below only mentions 7 applications and 5 zones.

    1. turn all the primary IP addresses into numbers (done) and then find a way (probably a index/match/if/and formula) to identify which IP falls into which subnet (number between numbers) and then retrieve the name of the associated security zone.

    2. create a list with all the IPs imaginable and then find a way to go through the list of primary and secondary IPs, retrieve the name of the application... then turn the IPs into numbers and find a way to identify which of them falls into which subnet and then retrieve the name of the security zone.

    The 2nd option seems far more precise, but both go beyond my excel skills when needing to find a number between 2 numbers and get the name of the security zone.
