Help with script

[mateusrico]

Hello friends
I need help, I have three files with thousands of subnets, sometimes I need to unlock an ip that is connected to some or some subnets.
I need a script that typing the IP look for these three files showing the subnets attached to that IP, removing the subnet automatically remove the block for the IP. the method I use currently allows me to find in which file the subnet is, but finding the subnet is not so easy.
I use linux ubuntu and the files are in "ipset" format, the script can be in bash, perl, python, etc ...
Thanks for the help.

I have no idea what ipset format is, but seems like this is an awk one-liner.

ipset format is
add country-name xxx.xxx.xxx.xxx/xx
add country-name xxx.xxx.xxx.xxx/xx

basically one subnet per line

Still not entirely sure what you're asking. Can you write out an actual line you want to change and what you want to change it to?

I need a script that finds the subnet related to it in a file containing several subnets of some sort.
./findip.sh 187.221.32.45 /root/country.txt
and as a result:
187.221.32.0/24
I do not have advanced knowledge in bash script to do it.
My language is Portuguese, I'm using google translate to write this.

Please upload one of those files here (if you can).

That includes subnetting arithmetic...
better yet
grep 187.221.32 /root/country.txt
then awk to exclude the country name if that is needed.

An educated guess anyway
