Xiaoyan Lin 9e76b5319e Fix testResolveIp to make it work in some special environment
Motivation:

As "getHostName" may do a reverse name lookup and return a host name based on the system configured name lookup service, testResolveIp may fail in some special environment. See #4720

Modifications:

Use getHostAddress instead of getHostName

Result:

testResolveIp works in all environments
