COS' default origin domain name is in the format of <BucketName-APPID>.cos.<Region>.myqcloud.com. By default, public network and intra-region private network access are supported. You can use this domain name to access COS over a private network (COS will be resolved to a private IP). In this case, traffic generated is private network traffic and will not incur traffic fees.
An example domain name is examplebucket-1250000000.cos.ap-guangzhou.myqcloud.com
. For more information on domains, see Regions and Access Endpoints.
