Error: dynamodb cannot assign requested address

Cannot assign requested address usually means the operating system could not assign the requested local address to a socket. Inspect the error code, syscall and address to determine whether a server bind or an outbound connection failed.

1. For bind errors, use an address present in that host or container. A host-only interface address is not automatically available inside Docker.
2. Use localhost for a client connecting to a service on the same host, or the service's network hostname between containers. A wildcard listener address is not a portable remote destination.
3. For connect errors under load, investigate exhausted local source ports or excessive connection churn. Reuse SDK clients and bound concurrency.
4. Check whether a separate message reports address already in use; that is a port collision and needs a different fix.

Changing DynamoDB IAM permissions or table capacity does not repair a local socket allocation failure. Capture the process configuration and network context, then retry after correcting the address or connection usage. If the service is reachable but returns an AWS error, diagnose that error separately.

See local networking setup and Node.js system-error reference.
