I understand that AWS Elastic IPs have a limit of 5 per region. I'm aware that I can request an increase in this limit through Service Quotas. However, I'm curious if the increase in quota is a concept of "slots", meaning the maximum allowable limit increases (for example, if all 5 are in use, the maximum limit increases to 10, allowing for the allocation of Elastic IPs to the remaining 5 slots when desired), or if Elastic IPs are immediately allocated and provided. Since AWS charges for unutilized Elastic IPs, I assume there would be no charge in the former scenario, but there might be in the latter.
I recognize that it's recommended to use up to 5 IPs per region and it's best to design with only 5 in mind. However, given my current situation, I am considering increasing the limit. Whether I'm charged solely for the increase will affect my decision.
I would greatly appreciate your response.

I appreciate your response. Regarding the slot concept, am I correct to understand that while the maximum limit can increase, actual charges are only incurred when the Elastic IP is allocated?
Exactly, you pay for allocated IP addresses when they are not associated with a running instance or when they are associated with a stopped instance or unattached network interface.
