Yes.

If a filter block it, you should avoid that one ASAP as the dev doesn’t know what he’s doing. 

For anyone else landing here, the reason it's getting blocked isn't that it's in a filter list, it's because it can get blocked due to "DNS Rebind" protection. Many AWS resources are private (like internal-only EKS, RDS endpoints) and accessible only over VPN. While the DNS records are public, they resolve to private IP addresses (eg: 10.1.2.3) depending on your service configuration. NextDNS will block DNS results that contain private IP addresses if you nave DNS Rebind protection enabled. Your options are either:

1. Disable DNS Rebind protection completely (bad)

2. Whitelist domains that resolve to private IP address ranges (better)
