java.security command

You can update specific Java Security related properties, such as the networkaddress.cache.ttl property.

You can specify the caching policy for successful name lookups from the name service. The value is specified as an integer to indicate the number of seconds to cache the successful lookup.

A value of -1 specifies to "cache forever". The default behavior is to cache forever when a security manager is installed, and to cache for an implementation-specific period, when a security manager is not installed.

Note: Setting this parameter to any value other than the default value can have serious security implications. Do not set this parameter unless you are sure that you are not exposed to DNS spoofing attacks.
