Can someone help me define the codes in this log entry?

What do the "200" & "113" numbers stand for on these entries - and what could this be? I have been getting these everyday from the same IP, around the same time each day for the last couple of months... is this something hacking/sniffing out openings on my server, or just a benign anomaly? Note the different computer configurations each day as well which seems odd...

The 200 code is the HTTP server status code.

200 is ok.. that is page request succeeded and sent.
113 is the size of the page in bytes.. excluding external files like CSS etc

If your going to be looking at your logs it's worth knowing the status codes
The full list is at [w3.org ]

That it was simply GET / suggests a request for your home page.
other requests are relative to /
