China DOS Union

I have a text file, name.txt, with only one line in it as follows:

B190

I wrote a batch file with the following contents:

@echo off

ping -a -n 4 -r 5 <<name.txt

@pause

When I run this batch file, it just flashes by, sweat, sweat
So I changed the bat, changing ping -a -n 4 -r 5 <<name.txt
to ping -a -n 4 -r 5 <name.txt
Then it shows: IP address must be specified.
I remember that on a Win98 machine I used <<, but now on WinXP I can't see any effect. What should I do? Is the command wrong?
At first I thought maybe you couldn't use a computer name and had to use an IP; but after I changed it to an IP, it was still the same effect, sweat, sweat, sweat, sweat. I'd appreciate some guidance from the seniors, many thanks!

Maybe you wrote it backwards, it should be >>, right.

No idea why this happens... let's wait together.

If it's urgent, use the temporary workaround below:
for /f %%i in (name.txt) do ping -a -n 4 -r 5 %%i

Many thanks to post #3.
Also thanks to post #2, but maybe post #2 didn't understand what I meant
