EC2 regional data transfer - in/out/between EC2 AZs question.

0

I have an EC2 instance in ap-northeast-1a, and my service is a trading program, so it will receive the market data from crypto exchange.

I find this in my bill:

$0.01 per GB - regional data transfer - in/out/between EC2 AZs or using elastic IPs or ELB 2,105.549 GB USD 21.06

It seems the network traffic is between different AZs? But I think they should in the same AZ ap-northeast-1a. The exchange only provides me some endpoints IPs, like 13.231.16.111, 52.195.97.237, 35.79.210.43. How to verify the real AZ of these IPs and avoid the cross AZ data transfer fee?

    This doesn't slove my problem, it only show me there's some inter AZ traffic, but I don't know the detail. More specific, my EC2 instance is at AZ ap-northeast-1a, I want to know this inter AZ traffic is come from ap-northeast-1b or ap-northeast-1c. The Cost Explorer doesn't show me that.
