180 Tracerts – All Output to 1 Text File?

I need to capture the output of about 180 different tracerts to a single text file. I’m using the sytax below, but it sends the output from each URL/IP to a different text file – which stinks.

tracert 207.71.25.21 >c:\25.21.txt
tracert 219.43.28.74 >c:\28.74.txt
etc….

I recall a batch command that will append the output of each into a single file – or am I wrong about this?

Thanks in advance for any replies.
