DNS Proxy Cache

When a DNS query is resolved by DNS proxy, the result is stored in the router's DNS cache. This stored cache helps the router to resolve subsequent queries from the same domain and avoid network latency delay.

Note: If the proxy cache is not available, the router sends the query to the configured DNS server, which results in network latency delays.

DNS proxy maintains a cache entry for each resolved DNS query. These entries have a time-to-live (TTL) timer so the router purges each entry from the cache as it reaches its TTL and expires. When you delete a domain name from the DNS proxy configuration, the router deletes all the entries associated with that domain name.

You can also clear the DNS cache manually with the following CLI command:
