+## Configure the JVM TTL for DNS name lookups
+
+The Java Virtual Machine (JVM) caches responses from successful DNS name lookups for a specified period of time, known as time-to-live (TTL). The default TTL value for many JVMs is `-1`, which means that the JVM caches the response indefinitely, or until the JVM is restarted.
+
+Because Azure resources use DNS names that can change, we recommend that you set the JVM TTL value to X seconds. This configuration ensures that any updated IP addresses for resources are returned with the next DNS query. You can change the TTL value by setting the `networkaddress.cache.ttl` system property.
+
+To change the TTL value globally for all applications using the JVM, set the `networkaddress.cache.ttl` property in the `java.security` file.
+
+```plaintext
+networkaddress.cache.ttl=X
+```
+
+For Java 8, the `java.security` file is located in the `$JAVA_HOME/jre/lib/security` directory. For Java 11 and higher, the file is located in the `$JAVA_HOME/conf/security` directory.

 ## Build your app
 
 As you build apps to work with data resources in Azure Blob Storage, your code primarily interacts with three resource types: storage accounts, containers, and blobs. To learn more about these resource types, how they relate to one another, and how apps interact with resources, see [Understand how apps interact with Blob Storage data resources](storage-blob-object-model.md).
