Before you update DNS settings and route all the traffic to Anti-DDoS Pro, we recommend that you verify the forwarding settings locally to guarantee availability.
Follow these steps to perform the verification:
Manually bind the virtual IP address provided by Anti-DDoS Pro with the domain name in your local hosts file (for example,
C:\Windows\System32\drivers\etc\hosts, in Windows). The domain name is then resolved to Alibaba Cloud’s IP address solely on your local device.
Refresh your local DNS cache. For example, run the
ipconfig/flushdnscommand at the command line interface in Windows.
Browse your website through the domain name in your browser.
- If the website is opened successfully, your configuration is properly set.
- Otherwise, check your configuration or open a ticket to contact Alibaba Cloud Technical Support.
