DNS caching timeout Apigee

Google Cloud Apigee

Hello

We use Apigee Edge private cloud. We have a use case where we want to provide security to our APIs hosted on AWS (Private) EC2 instances. These EC2 instances will be behind ELBs, which are spread across at least 2 AZs. Apigee will use a A Record to connect to any one of the ELBs. Now does Apigee inherit the default DNS TTL configured as part of A Record or does it have a default DNS caching TTL configured somewhere?

Thanks -Nitin

networkaddress.cache.ttl is configured in jre/lib/security/java.security. This property is explained at https://docs.oracle.com/javase/7/docs/api/java/net/InetAddress.html. In short 0 indicates no caching, -1 indicates cache for ever and a positive integer indicates the number of seconds to cache the DNS look up.

Hey Sathish,

We’ll get our Ops team look into this setting. Thanks for your input.
