Question

Does traffic between droplets in same VPC accessed via public ips count as incoming traffic?

From my understanding on VPC and bandwidth usage - traffic between droplets within a VPC doesn’t count towards the bandwidth quotas.

Does this count when droplets connect via the private ips only? Does accessing a droplet via its public ip also count?

Hello,

In your case, it is best to use the private network interface.

Any data transfer sent by a Droplet using a public network interface will count against the transfer pool for that Droplet’s account. All IPv6 traffic uses the public interface. Data transfer between Droplets over the VPC network uses a private network interface.

Best,
