bing in Brazil

[lucy24]

I thought for sure there was a thread about it but I'm ### if I can find it.

We know about Microsoft's LACNIC IP
191.232.0.0/14
but since when has the bona fide bingbot been using it?

Today's log-wrangling--going back to the 29th--reveals a clutch of bingbot visits ... including requests for URLs (both pages and images) that they know darn well have been redirected for more than 2 years. No requests for robots.txt from this IP, but otherwise unquestionably the real thing:

Mozilla/5.0 (compatible; bingbot/2.0; +http://www.bing.com/bingbot.htm)

wtf?

It was a while ago- April 15, 2014: [webmasterworld.com...]

191.232.0.0 - 191.239.255.255
Brazil
Microsoft Informatica Ltda

I'm seeing much more of bing, but not this one. yet.

So far I've only seen it from 191.232.136.0/24( 191.232.136.0 to 191.232.136.255 ). For me started on 28th of last month. But apparently it has has been in USE for a while: [newsgroup.lilobzh.com...]

Same here. In fact, so far only 191.232.136.0/25 (..136.127-or-less) but I don't suppose they'll stick with that narrow a range. I find a couple on one site on the 28th and then they got busy on the 29th.

The rest of the /14 seems limited to assorted unwanted visitors. That is, genuinely undesirable robots, not the plainclothes bingbot.

191.232.136.24 - - [29/Jan/2016:00:43:58 -0800] "GET /page.html HTTP/1.1" 200 2984 "-" "Mozilla/5.0 (compatible; bingbot/2.0; +http://www.bing.com/bingbot.htm)"

The problem is that while this is a valid crawl range: msnbot-191-232-136-24.search.msn.com... Other sub-ranges of the /14 show as Microsoft's Azure Cloud in Brazil & can be leased by anyone (think AWS.) This is why there are so many spam & hack reports at webhoneypot, spamhaus & other reporting agencies.

So maybe a more surgical approach w/ a few conditions is need for:
191.232.0.0 - 91.235.255.255
191.232.0.0/14

BTW, this MS block is actually much larger including other MS assignments:
191.232.0.0 - 191.239.255.255
191.232.0.0/13
