You can check for the cache size using the below commad: show recursion_cache_size. 

 

A DNS server caching a record will return the TTL after reducing the time the record was cached by the server. If the Original TTL of the record is X seconds and a query is received after y seconds of caching, the caching server will return a TTL of (x-y)
