AWS VPC DNS主机名打开或关闭

Question

I'm starting to work with a non-default VPC that has DNS Hostnames set to off. I need to turn this on so I can add an RDS instance into the VPC. I know I can do this from the VPC console but my question is what are the implications of this change? What is the possible effects of this on what is already working and could it cause elements to stop working? Basically, this VPC is simple enough with 3 subnets, there are 3 EC2 instance webservers working, each with a set of elastic IP addresses assigned to them with different private IP addresses, as all machines are running a handful of different websites.

Any advice appreciated. Thanks

名称解析将是需要考虑的主要方面，如果您需要或计划在您的服务器中使用DNS，de DNS主机名设置为每个实例将具有亚马逊提供的名称，您不需要自己做，但如果您需要特定的DNS名称到这个实例，您可以将DNS主机名关闭，并安装自己的DNS服务器
