Domain name binding

Last updated:2021-10-18 16:00:50

Kingsoft Cloud Standard Storage Service (KS3) allows you to bind custom domain names to your buckets. Then, you can access the objects in the buckets by using the custom domain names. This allows you to seamlessly migrate your data to KS3 and protect the security of KS3 domain names. After a custom domain name is bound to a bucket, you need to add a CNAME record to map the custom domain name to the public domain name of the bucket. Then, you can use the custom domain name to access the bucket.


  • You must apply for an ICP filing from the Ministry of Industry and Information Technology (MIIT) of China for the custom domain name to be bound. Otherwise, the binding will fail.
  • You cannot bind a custom domain name to two or more buckets in the same region within the current account.
  • You can bind up to 50 domain names to a bucket.
  • A bucket can have up to 50 domain name binding records, including successful binding records and the records of failed binding due to reasons such as domain name conflict or no ICP filing.
  • After a custom domain name is bound to a bucket, you do not need to enter the bucket name in the access URL when you access objects in the bucket by using the domain name.
  • You cannot configure certificates for custom domain names in the KS3 console. You need to perform this operation in the CDN console.
