Analyze AWS NAT cost

122 Views Asked by At

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?

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)
