When using DNS, a system might store the DNS mappings to its cache to speed up the query. There are three ways to obtain DNS mappings:

Dynamic: Obtains from DNS response.
Static: Adds DNS mappings to cache manually.
Register: DNS hosts specified by some modules of Hillstone devices, such as NTP, AAA, address book, etc.

In the Cache page, you can perform the following actions:
