As Netflix is using Amazon AWS too (https://blog.thousandeyes.com/how-netflix-tracks-ip-addresses-within-aws/), you might want to use those IP ranges as well.
https://aws.amazon.com/blogs/aws/aws-ip-ranges-json/

I have updated the IPv4 script in a somehow clumsy way to accomodate all these ranges, allowing them to be used for policy routing.

#!/bin/bash
# Gather Netflix and Amazon AWS IP ranges and put them into single file

set -e
if [ -e getflix.txt ] ; then rm getflix.txt ; fi
# This command finds the ASNUMs owned by netflix
curl -s https://geolite.maxmind.com/download/geoip/database/GeoLite2-ASN-CSV.zip >nflix.zip
for as in $(unzip -p nflix.zip `unzip -l nflix.zip |grep -e GeoLite2-ASN-Blocks-IPv4.csv | sed 's/^.\{30\}//g'` | grep -i netflix | cut -d"," -f2 | sort -u)
    do
    whois -h whois.radb.net -- '-i origin AS'$as | grep -Eo "([0-9.]+){4}/[0-9]+" | tee netflix_ranges.txt >>getflix.tmp
done

# Get the Amazon AWS ip range list
curl -s https://ip-ranges.amazonaws.com/ip-ranges.json |grep ip_prefix |cut -d"\"" -f4 >>getflix.tmp

# unify both the IP address ranges
cat getflix.tmp | sort -u >getflix.txt
#tidy the tempfiles
rm nflix.zip
rm getflix.tmp

Yet to confirm: this list is definitely NOT complete, as there are ISPs who transparently cache the Netflix traffic - greetings to O2 Czech/ IP 194.228.248.66, so you have to investigate by yourself.

Now you have to change the first curl line to:

curl -s 'https://download.maxmind.com/app/geoip_download?edition_id=GeoLite2-ASN-CSV&license_key=YOUR_LICENSE_KEY&suffix=zip' >nflix.zip

@corredor28 Hi! Where can I find the license key ? Thanks, Alex

I have made an updated list of Netflix IP's (not using the MaxMind database). Doing this I've also noticed the original list contains some fully overlapping ranges, for example the top two:

from ipaddress import ip_network
ip_network('108.175.34.0/24').subnet_of(ip_network('108.175.32.0/20'))
# returns True

At first glance it therefore might seem that some entries from the original list are missing, but they are probably still in the list of ranges below:
