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 way, malicious requests can be blocked by region. This topic describes how to configure a region blacklist or whitelist.
