Does COS have a private network domain?
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, for example, examplebucket-1250000000.cos.ap-guangzhou.myqcloud.com. For more information on domain name, see Regions and Access Endpoints. You can use this domain to access COS over a private network (COS will be resolved to a private IP).
In this case, the following will be generated:
Private network traffic: Both private network upstream traffic and downstream traffic are free of charge. For more information, see Traffic Fees. Requests: The total number of read requests and write requests are calculated every day according to the number of times a request command is sent, with 10,000 times as the minimum unit. For more information, see Request Fees.
