I used the docs I found online to analyze the main contributors to the NAT gateway huge!!! cost. So I have now a list of IPs, but I can't determine to who each one belongs. I am using some 3rd party apps that might be related to the IPs, but I am struggling to find their possible ranges of IPs. For example (Confluent Kafka, Snowflake and more). Any thoughts?

You could try using one of the many online IP lookup/WHOIS tools – NickW Dec 26 '22 at 13:31

Unix terminal usually includes whois:
whois 12.46.8.0
which looks up the IP owners in a registry. ex. the above IP belongs to AT&T
NetRange: 12.0.0.0 - 12.255.255.255
CIDR: 12.0.0.0/8
NetName: ATT
...
Organization: AT&T Services, Inc. (ATTW-Z)
Another great tool is GeoIP lookup by Maxmind. This gives you a location AND the registered organization. https://www.maxmind.com/en/geoip-demo
