It will return get host error without this change. It's miss-leading report to end user. It's also quite common practice for linux to use one ping support both ping and ping6. ## Testing attach two network packet that packet losing for either v4 or v6. <img width="1812" height="175" alt="image" src="https://github.com/user-attachments/assets/63cde99e-08b1-4897-8f35-69e828e36e84"; /> <img width="1814" height="201" alt="image" src="https://github.com/user-attachments/assets/a7ee3ad9-085b-4897-8c84-82dbac39bb71"; /> Error log attached as below: ping -c 5 www.baidu.com ERROR: ping_gethostip(www.baidu.com) failed -- This is an automated message from the Apache Git Service.
