    You'll get better log data if you set "HostnameLookups off" in your
    Apache (I assume you're running Apache) config file. Whatever IP has
    been hitting you has number->name DNS set to point to gw.ocg-corp.com,
    but since ocg-corp.com dosen't exist (and Apache dosen't verify that
    results it gets from number->name lookups are valid before logging
    them), the log entry is mostly worthless for determining source.
    
    But...
    
    A grep of my web server logs for 'larbin' turned up 14 entries so far
    today, all from 209.126.176.3, which may be your match:

    Address: 209.126.176.3
    
    $ host gw.ocg-corp.com
    gw.ocg-corp.com does not exist, try again

    However, it wasn't hitting my server anywhere near hard enough to
    cause problems. Except for requests for robots.txt, which usually were
    immediately followed by another request, the minimum time observed
    between requests was a respectable 30 seconds, and it seemed to obey
    the restrictions given in my robots.txt.
    
    
    Larbin (http://larbin.sourceforge.net/index-eng.html), the program
    hitting your server, is a web crawler.
