APACHE access logs

[IBhacknU]

I know this is the OT forum, but there are so many sharp minds here. My question is as follows:

searching my access logs, I find this:

216.35.103.80 - - [24/Oct/2000:07:34:59 -1000] "GET /robots.txt HTTP/1.0" 404 283
216.35.103.80 - - [24/Oct/2000:07:35:21 -1000] "GET / HTTP/1.0" 200 1788
216.35.103.79 - - [24/Oct/2000:07:39:03 -1000] "GET /robots.txt HTTP/1.0" 404 283
216.35.103.79 - - [24/Oct/2000:07:39:35 -1000] "GET / HTTP/1.0" 200 1788
216.35.103.81 - - [24/Oct/2000:07:50:26 -1000] "GET /robots.txt HTTP/1.0" 404 283
216.35.103.81 - - [24/Oct/2000:07:50:47 -1000] "GET / HTTP/1.0" 200 1788

and then this....

213.216.143.39 - - [25/Oct/2000:03:18:30 -1000] "GET /robots.txt HTTP/1.0" 404 283
213.216.143.39 - - [25/Oct/2000:03:18:32 -1000] "GET / HTTP/1.0" 200 1788
213.216.143.37 - - [25/Oct/2000:05:18:04 -1000] "GET /robots.txt HTTP/1.0" 404 283
213.216.143.37 - - [25/Oct/2000:05:18:05 -1000] "GET / HTTP/1.0" 200 1788


Is this a web crawler?

EDIT: Note to self, learn to spell!
