EC2 实例没有公共 DNS [英] EC2 instance has no public DNS

问题描述

一个与我共事的人给了我 EC2 凭据以登录他的 EC2 控制台.我不是设置它的人.一些实例显示公共 dns 名称，而其他实例显示空白公共 DNS.我希望能够连接到具有空白公共 DNS 的实例.我一直无法弄清楚为什么这些显示为空白.

A guy I work with gave me the EC2 credentials to log onto his EC2 console. I was not the one who set it up. Some of the instances show a public dns name and others have a blank public DNS. I want to be able to connect to the instances that have a blank public DNS. I have not been able to figure out why these show up as blank.
