Domain Name

Description

You can enter multiple domain names.
  • Domain names are separated by spaces.
  • Each domain name can contain one or more character strings separated by periods (.). Each character string can contain a maximum of 63 characters. For example, the domain name test.com has two character strings test and com.
  • The total length of all domain names cannot exceed 254 characters.
To access a domain name, you only need to enter the domain name prefix. ECSs in the subnet automatically match the configured domain name suffix.
  • If the domain names are changed, ECSs newly added to this subnet will use the new domain names.
  • If an existing ECS in this subnet needs to use the new domain names, restart the ECS or run a command to restart the DHCP Client service or network service.
    • Restart the DHCP Client service: service dhcpd restart
    • Restart the network service: service network restart
      • The commands for updating the DHCP configuration depend on the cloud server OS. The commands here are only for your reference.
      • If the DHCP configuration is not updated, domain name changes take effect when existing cloud servers renew their DHCP lease before it expires. Learn more
