  - cacheMaxTimeToLive
```
NameResolverProvider.NameResolverSpec cacheMaxTimeToLive(Duration cacheMaxTimeToLive)
```
    Sets the max time to live of the cached DNS resource records (resolution: seconds). If the time to live of the DNS resource record returned by the DNS server is greater than this max time to live, this resolver will ignore the time to live from the DNS server and will use this max time to live.

```
    Sets the min time to live of the cached DNS resource records (resolution: seconds). If the time to live of the DNS resource record returned by the DNS server is less than this min time to live, this resolver will ignore the time to live from the DNS server and will use this min time to live. Default to Build#DEFAULT_CACHE_MIN_TIME_TO_LIVE.
    
    Parameters:
    
    cacheMinTimeToLive - the minimum time to live (resolution: seconds)
