How to determine IP address for device in S602nd fp3

[swarupk2007]

Hi guys i want to determine IP address of handset so please tell me
how to get that information in s60 2nd FP3

TInetAddr aAddr;
RSocket sock;
TBuf8<20> aIP8;
TBuf<20> aIP;
User::LeaveIfError(sock.Open(socketServ, KAfInet, KSockStream, KProtocolInetTcp));

// Get the IAP id of the underlying interface of this RConnection
//TUint32 iapId = 0;
//User::LeaveIfError(conn.GetIntSetting(_L("IAP\\Id"), iapId));

// Get IP information from the socket
TSoInetInterfaceInfo ifInfo;
TPckg<TSoInetInterfaceInfo> ifInfoPkg(ifInfo);
TSoInetIfQuery ifQuery;
TPckg<TSoInetIfQuery> ifQueryPkg(ifQuery);
// To find out which interfaces are using our current IAP, we must
// enumerate and go through all of them and make a query by name for each.
User::LeaveIfError(sock.SetOpt(KSoInetEnumInterfaces, KSolInetIfCtrl));

while(sock.GetOpt(KSoInetNextInterface, KSolInetIfCtrl, ifInfoPkg) == KErrNone) {

ifQuery.iName = ifInfo.iName;
TInt err = sock.GetOpt(KSoInetIfQueryByName, KSolInetIfQuery, ifQueryPkg);
if( err == KErrNone && ifQuery.iZone[1] == g_iapId)
{ // IAP ID is index 1 of iZone
// We have found an interface using the IAP we are interested in.
//if( ifinfo.iAddress.Address() >0 )
if (!ifInfo.iAddress.IsUnspecified() && !ifInfo.iAddress.IsLoopback() && !ifInfo.iAddress.IsLinkLocal())
{

// found a IPv4 address
aAddr = ifInfo.iAddress;
aAddr.ConvertToV4();
aAddr.Output(aIP);

aIP8.Copy(aIP);

strncpy(out,(char*)aIP8.Ptr(),aIP8.Length());


sock.Close();
return err; // stop & return KErrNone
}
}
else if( err !=KErrNone ) {
sock.Close();
return err; // return with error
}
} // while
sock.Close();
return KErrNotFound; // return with KErrNotFound

Whats wrong with this code?
I am calling this after establishing connection.
it shows Inside GetIPAddress
after that no message displayed
