🤖 Ai回答: To determine the number of domains in a DNS集群, we need to understand the structure of a DNS集群、A DNS集群 typically consists of a root domain and several subdomains、The root domain is the top-level domain, and the subdomains are nested within the root domain.
Let's break it down step by step:
1、Identify the root domain、This is the top-level domain in the cluster.
2、Identify the subdomains、These are the domains that are nested within the root domain.
3、Count the total number of domains, which includes the root domain and all the subdomains.
For example, if we have a root domain ` 65.hk` and three subdomains ` 65.hk/a`, ` 65.hk/b`, and ` 65.hk/c`, the total number of domains in the cluster is:
The root domain: ` 65.hk`
The subdomains: ` 65.hk/a`, ` 65.hk/b`, ` 65.hk/c`
