There have been earlier threads about TencentTraveler. Is it a browser? Is it a robot? Is it a toolbar? Who cares. ::yawn:: Mine tend to come from blocked IPs, so I haven't paid much attention to them.
The last one caught my notice because it came from 216. On closer investigation:
Now, I've always assumed, on no evidence whatsoever, that (a) anything with "rack" in its name is a colo and (b) it can safely be blocked on those grounds alone. So that was useful.
This particular visitor came from a /28 subrange attributed to "Chantilly" which I think is a euphemism for "I don't want to say". (I looked it up once. Chantilly is a suburb of Washington DC, so it could mean anything.) But even the free lookup admits that what we've really got is a private party living in China.
Funny how that works.
P.S. While I was at it, I added "TencentTraveler" to the BrowserMatch list. Who needs 'em.
And, if anyone cares: It picked up only a page, no associated files. The exact UA-- complete with ; spaces and (hiccups) --was: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; TencentTraveler ; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ; .NET CLR 2.0.50727)
