我试图将CNAME指向一个S3存储桶,但是仍然遇到nslookup(以及我的浏览器)找不到CNAME的问题.
但是,当我使用dig时,它会显示域的正确输出.我相当肯定我在这里错过了一些愚蠢但我似乎无法找到问题:(
任何帮助表示赞赏！

解决方法
似乎Google DNS无法解析您的CNAME,因为它指向的主机名本身无法解析：
# nslookup imgs3-website-eu-west-1-amazonaws.com 8.8.8.8 Server: 8.8.8.8 Address: 8.8.8.8#53 ** server can't find imgs3-website-eu-west-1-amazonaws.com: NXDOMAIN
