@DanielCastronovo you should be using Prefix Delegation which will expand the number of IPs available on a node by quite a lot
https://docs.aws.amazon.com/eks/latest/userguide/cni-increase-ip-addresses.html
and you should monitor for running out of IPs in the subnets.

@njtran i don't think it is related to subnets, but to ec2 ENI capacity.

Agreed, was pointing to your comment about running out of IPs in the subnets.

I was just trying to provide extra general guidance
