Hi Akash,

You may use dumpbin.exe tool to examine the import API list of
ipconfig.exe. This will help to enlighten what APIs ipconfig used to get
various network information. Some of the interesting APIs I got:

iphlpapi.dll
     76CF4B66     1B GetAdaptersAddresses
     76CFE024     6F NhGetInterfaceNameFromGuid
     76CF2DF4     2E GetInterfaceInfo
     76CF6264      2 AllocateAndGetIfTableFromStack
     76CF4966     2F GetIpAddrTable
     76CF6B05     32 GetIpForwardTable
     76CF5A67     70 NhpAllocateAndGetInterfaceInfoFromStack
     76CF6748     3A GetNetworkParams
     76CF6BA8     36 GetIpStatistics

netman.dll
     77842FCA      5 HrPnpInstanceIdFromGuid
     778417B6      4 HrLanConnectionNameFromGuidOrPath

   DNSAPI.dll
     76EE678F     25 DnsGetCacheDataTable
     76ED9E13     22 DnsFree
     76EE347F     49 DnsQuery_W
     76ED403F     4E DnsRecordListFree
     76EEAB37     1E DnsFlushResolverCache
     76ED3CA0     42 DnsQueryConfigAllocEx
     76ED9DA6     23 DnsFreeConfigStructure

If you wanted to get more information about using these IP helper APIs,
please refer to the article below:
"More on using IP Helper API's"
http://www.codeproject.com/KB/IP/IPHelper.aspx

Finally, this newsgroup may focus on the C++/CLI programming language
related questions. You'd better post in
microsoft.public.win32.programmer.networks newsgroup to get more
professional helpful from the network experts there. Thanks.

Best regards,
Jeffrey Tan
