Guys, who can tell me what's wrong? Created a bash script to automatically generate an ip pool in nethash format (subnets). But at the output, the list is obtained both with individual ip and with subnets. Example 40.87.183.236/31 51.120.224.192/28 51.141.8.62 104.46.121.72 ...

I don't understand why separate ip's are formed as well, because the initial loaded list only contains subnets.

#!/bin/bash
echo "### Blocking Microsoft ###"
# Delete the list if it already exists
ipset -X blacklist
#Creating a new list
ipset -N blacklist nethash
# Download the files of the countries we are interested in and merge them into one list
wget -O microsoftIPv4-agrig.zone https://raw.githubusercontent.com/lord-alfred/ipranges/main/microsoft/ipv4.txt
echo -n "Uploading blacklist to IPSET"
# Read the list of networks and add them to ipset line by line
list=$(cat microsoftIPv4-agrig.zone)
for ipnet in $list
do
ipset -A blacklist $ipnet
done
echo "completed"
