How do DNS translations work with Inter-Region VPC Peering?
DNS 轉譯與區域間 VPC 對等如何搭配運作？
By default, a query for a public hostname of an instance in a peered VPC in a different region will resolve to a public IP address. Route 53 private DNS can be used to resolve to a private IP address with Inter-Region VPC Peering.
根據預設，針對不同區域中對等 VPC 執行個體公有主機名稱的查詢會解析為公有 IP 地址。Route 53 私有 DNS 可用來解析為含區域間 VPC 對等的私有 IP 地址。
