Dynamic Route for CDN (DCDN) supports the region blacklist and whitelist. After you add regions to a blacklist or a whitelist, DCDN identifies the source regions of requests and blocks or allows requests from the specified regions. This allows you to block malicious requests by region. This topic describes how to configure a region blacklist or whitelist.

Notice The region blacklist or whitelist feature is suspended. We recommend that you use DCDN WAF (new edition).
