The Symbian Sockets RecvFrom function returns the IP Address in TInetAddr.To check how to get the Ip Address you can refer the following link LocalDeviceIpAddress

If you are aware of all the API's in TInetAddr then converting this to TBuf is not the problem, but if you are not aware then you can refer the below code .

PreRequities

TInetAddr address contains the IP Address obtained by using RecvFrom function of RSocket .

TInetAddr to TBuf

TInetAddr address;
TBuf <16> ipAddr;
 
TInetAddr :: Cast(address).Output(ipAddr);
// ipAddr  now contains  the IP Address.

Converting IpAddress to Char*

char* fromaddr;
//ipAddr = TBuf that we got from  above code 
for (i = 0; i < ipAddr.Length(); ++i )
{
  fromaddr[i] = char(ipAddr[i]);
}
fromaddr[i] = '\0';
