Tencent Cloud accounts include bill-by-IP and bill-by-CVM accounts. We recommend that you upgrade your bill-by-CVM accounts to bill-by-IP accounts as the former cannot support new features later.
Note：Note: Downgrading from "bill-by-IP" to "bill-by-CVM" is not allowed.
Checking Account Type
All Tencent Cloud accounts registered after June 17, 2020 00:00:00 will be bill-by-IP accounts. For Tencent Cloud accounts registered before June 17, 2020, check your account types in the console.

- Bill-by-CVM account manages bandwidth and traffic on CVM. For such an account, network bandwidth and traffic can be purchased on CVM, instead of public IP or CLB.
Account Upgrade
Advantages
A comparison between the advantages of bill-by-IP and bill-by-CVM accounts is shown below:
| Item | Bill-by-IP account | Bill-by-CVM account |
|---|---|---|
| Whether the network bandwidth under the account can be migrated to other CVM instances | Yes, as the public network fees are billed by IP. | No, as the public network fees are billed on the bound CVM instance. |
| Elastic IPv6 billing | IPv6 and IPv4 can be added into the same bandwidth package and billed together. | IPv6 can only be billed separately. |
| NAT gateway billing | Bill by traffic and bill by bandwidth package are supported. | Only bill by traffic is supported. |
| Is it necessary to purchase public network for CLB backend CVM | No. Only bandwidth needs to be purchased for CLB, which facilitates management. | Yes. Purchasing public network for all CLB backend CVMs is needed, which complicates management. |
| New network-related features | Both the existing and new features are supported. | Only the existing features are supported. |
