Hello! My app is hosted at a dedicated/static IPv4 address. Is it possible to make outbound connections from the same address? (And if not, can I request for this feature?)
For context, I’m running a DNS server (BIND 9) on Fly. It’s the primary nameserver for my domain, and I use a third-party provider to host the secondary. When I deploy updated DNS records, the primary sends a DNS NOTIFY message to the secondary. Right now, that message is being rejected because it originates from a random Fly IP address in the outbound pool, and the provider (and most DNS software in general) only accepts NOTIFYs from the IP address of the configured primary. So my understanding is that hosting a DNS nameserver requires serving inbound and outbound traffic from the same IP address.
Thanks!
