Getting these on one of my web servers on an almost daily basis: 114.232.243.86 - - [01/Sep/2014:09:51:34 -0400] "GET http://hotel.qunar.com/render/hoteldiv.jsp?&__jscallback=XQScript_4 HTTP/1.1" 404 15 "http://hotel.qunar.com/" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36" The traffic comes from all sorts of different IPs that are owned by China Telecom. 114.232.243.86, 114.231.42.219, 222.209.137.232, 222.209.152.192, 118.113.227.95. The host I am seeing this on does not need to speak to anyone or anything in China, so I used IPTables to filter the entire netblocks I see hits from. Here is an example of a filtering rule along with a little note for myself. Notice that this rule assumes two nonstandard chains - BLACKLIST and LOGDROP - that I use to organize my ruleset. -A BLACKLIST -s 114.224.0.0/12 -m comment --comment "Chinanet Hotel Qunar Referrer" -j LOGDROP Beca
