Question

I’m using the AWS SDK for .NET and I noticed that when I stop-start a server the elastic IP is de-associated from the instance. In my program I know what the elastic IP is but how can I re-associate it from the tools?

Answer 1

I am not a .NET programmer so I can’t write you example code.
You can use the AssociateAddressRequest class which resides in the Amazon.EC2.Model namespace

This would look like this

String instanceId = "your instance id";
String publicIp = "your public ip";

ec2.associateAddress(new AssociateAddressRequest()
            .withInstanceId(instanceId)
            .withPublicIp(publicIp));

Found an example usage here: method process_assign_address_command line 593

EDIT:

Offtopic, but still might interest you: this is how I found the code example.

Hope this helps 🙂
