Custom Device Domain Name

Overview

A custom fully qualified domain name (FQDN) for a device to connect to IoTDA. With a custom domain name, you can manage your own server certificates, including the root certificate authority (CA), signature algorithms, and certificate lifecycles.

Scenarios

• Managing the root CAs, signature algorithms, and certificate lifecycles of server certificates.
• Disclosing the domain names to customers for branding.
• Inheriting the original domain names and server certificates during migration.

Constraints

• Only the standard and enterprise editions support this function.
• Only port 8883 connected using MQTT takes effect.
• The device must use TLS and support SNI (Server Name Indication). The SNI must carry the required custom domain name.
• Only one custom domain name can be configured for an IoTDA instance.
