通过机器名得到IP地址

function procedure TForm1.nametoip(name:string):string;
var
  WSAData: TWSAData;
  HostEnt: PHostEnt;
begin
  result:=';
  WSAStartup(2, WSAData);
  HostEnt := gethostbyname(PChar(name));
  if HostEnt <> nil then
  begin
    with HostEnt^ do
     result:= Format('%d.%d.%d.%d', [Byte(h_addr^[0]), Byte(h_addr^[1]), Byte(h_addr^[2]), Byte(h_addr^[3])]);
    end;
    WSACleanup;
end;

通过IP地址得到机器名

function iptoname(ip:string):string;
var
  WSAData:TWSAData;
  p:PHostEnt;
  InetAddr:dword;
begin
  WSAStartup(2, WSAData);
  InetAddr:= inet_addr(PChar(IP));
try
   p:=GetHostByAddr(@InetAddr, Length(IP), PF_Inet);
   result:=p^.h_name;
  except
   result:=';
  end;
end;
