I set up a copy of nginx returning 404s on that port.  After a few thousand
requests, here are the hostnames it is trying to hit:

   4655 ib.adnxs.com
   2193 ad.globe7.com
   1705 ads.creafi-online-media.com
   1149 ad.tagjunction.com
    767 ad.yieldmanager.com
    259 an.z5x.net
    184 ad.z5x.net
    123 ad.xertive.com
    115 ib.reachjunction.com
     80 tags1.z5x.net
     72 ad.bharatstudent.com
     71 ad.reduxmedia.com
     23 ad.smxchange.com
     18 opt.cdxndirectopt.com
     10 www.xtendadvert.com

It might be worth digging up the security contact for at least the top few
of those and give them a heads up.

And the /24s that have sent at least 100 requests (of 811 unique IPs from 122
/24s):

    108 208.115.246.0/24
    103 74.63.199.0/24
    100 63.143.59.0/24

These are very unlikely to have been spoofed, as they were from completed 
TCP connections.
