DNS_ERROR_NEED_SECONDARY_ADDRESSES - 9614 (0x258E)

Need secondary IP address.

Updated: Feb 21, 2026

Technical Background

The DNS_ERROR_NEED_SECONDARY_ADDRESSES error code, with the numeric value of 9614 and hexadecimal representation 0x258E, is a specific error encountered during DNS configuration in Windows. This error indicates that secondary IP addresses are required for proper DNS operation.

Error Details

This error typically arises when attempting to configure or manage DNS settings where secondary IP addresses are necessary but not provided. Secondary IP addresses play a crucial role in load balancing and failover scenarios, ensuring redundancy and reliability in network configurations.

Common Causes

  • Invalid Parameter Values: The configuration attempt did not include the required secondary IP addresses.
  • Incorrect Object Type: The operation was performed on an object type that requires secondary IP addresses but was not properly identified or configured.
  • Exceeding Limits: The system may have limitations on the number of IP addresses that can be assigned, and this error could indicate a limit has been reached.

Real-World Context

In network environments where redundancy is critical, such as in enterprise setups with multiple DNS servers or load-balanced services, secondary IP addresses are often required. This error ensures that configurations are properly set up to handle failover scenarios and maintain service availability.

Is This Error Critical?

The DNS_ERROR_NEED_SECONDARY_ADDRESSES error can be critical if the operation is part of a setup where redundancy is essential. However, it does not necessarily indicate a severe system failure; rather, it highlights a configuration requirement that must be addressed to ensure proper functionality.

How to Diagnose

To diagnose this issue, follow these steps:

  1. Review Operation Context: Ensure the operation context is correct and aligns with the requirements for secondary IP addresses.
  2. Validate Parameters: Verify that all required parameters, including secondary IP addresses, are correctly specified in the configuration.
  3. Confirm Object Types: Confirm that the object types being configured support secondary IP addresses.
  4. Verify Input Data: Check the input data to ensure it includes all necessary secondary IP addresses.
  5. Check Limits or Constraints: Ensure that no system limits have been reached, such as maximum number of IP addresses per interface.

How to Resolve

To resolve this issue, take these actions:

  1. Correct Parameter Usage: Ensure all required parameters are correctly specified during configuration.
  2. Adjust Operation Context: If the operation context is incorrect, adjust it to align with the requirements for secondary IP addresses.
  3. Restore Data: If data corruption or missing information is suspected, restore from a backup if available.
  4. Retry Operation with Valid Inputs: Reattempt the configuration with all necessary secondary IP addresses included.

Developer Notes

Developers should ensure that their applications and configurations are aware of the need for secondary IP addresses in scenarios where redundancy and failover are critical. This error code serves as a reminder to include these details during setup or modification processes.

  • DNS_ERROR_NAME_DOES_NOT_EXIST (9613, 0x258D): Indicates that the specified domain name does not exist in DNS records.

FAQ

Q: What causes the DNS_ERROR_NEED_SECONDARY_ADDRESSES error?

A: This error occurs when secondary IP addresses are required but not provided during DNS configuration. Ensure all necessary parameters, including secondary IP addresses, are correctly specified.

Q: Is this error critical for system operation?

A: While it can be critical in scenarios requiring redundancy and failover, the error itself does not indicate a severe failure. It highlights a configuration requirement that must be addressed to ensure proper functionality.

Summary
