When you setup a AWS PrivateLink Endpoint, you get a hostname to target. E.g. com.amazonaws.vpce.us-east-2.vpce-svc-123xyz567 which resolves to a private IP in the subnet you create it in, e.g. 192.168.0.1. Do those change? It seems likely we're given a hostname, but does it happen in practice?
For example, if I have limitation in a legacy system that it can only target an IP address and not a hostname, how likely/often is it that I would need to update?
