Before You Start¶
DNS provides a set of functions for different scenarios.
When DNS Is Required¶
You can select a type of function based on Table 1 to suit your network scenario.
Function | Scenario | Reference |
|---|---|---|
Public domain name resolution | Domain names are mapped to the public IP addresses of web servers or web applications on the Internet so that end users are routed to your website or application. | |
Private domain name resolution | Domain names are mapped to the private IP addresses within the VPCs for accessing cloud resources or cloud services over a private network. | |
Reverse resolution | EIPs are mapped to domain names, which is often used by email servers against spammers. |
