Nice of them to make it appear legit.

Why do you think it appears legit? Anything amazon should be blocked with prejudice! They host hundreds of nasty little me-too bots. There are a couple (at least) threads hereabouts giving full IP ranges.

The Search utility at the top of the page is a great tool to verify if a topic has been discussed before. Often times, if members wish to add more info to a previously discussed topic that has now been closed, they will reference that specific discussion as a link in their post.

Amazon EC2 & its ranges may have been the most discussed topic within the Search Engine Spider and User Agent Identification Forum.

107.20.0.0/14

I've just this instant (really) come from updating my shared htaccess*, and would have been awfully annoyed if it turned out I'd missed one. Gosh, what a lot you can shave off the filesize by putting multiple Deny-froms in a single line, as in

Deny from 1.3 1.8 1.12.0.0/14 1.24.0.0/13 1.45 1.48.0.0/14
Deny from 1.50.0.0/14 1.56.0.0/13 1.68.0.0/14 1.80.0.0/12
Deny from 1.116.0.0/14 1.180.0.0/14 1.184.0.0/15 1.188.0.0/14 1.192.0.0/13
Deny from 1.202.0.0/15 1.204.0.0/14

(Not AWS, obviously, but same principle. Cut the size by 1/3, and I didn't even consolidate very much.)


* Multiple domains in the same userspace. You can't do everything in a shared htaccess-- and some things you wouldn't want to-- but consolidating the mod_auth_whatsit is a huge timesaver.

When I consolidated mine, it went from 36k to 19k. (but I also broadened many ranges to include smaller ranges, mostly Chinese.)

When I said legit, I ment that they are attempting to look like maybe a yellow pages bot or something.

I don't mean to annoy anyone here with my posts but with a site with very heavy traffic I like to share the odd user agents that come along for those that are bot blockers.

You never know when it will come through some proxy or something.

I have my system arranged such that it checks not only the actual IP but any proxy IPs as well. If a proxy IP is in a blocked range (server farm, high-abuse-rate IP etc) then the actual IP is blocked as well: it usually means the idiot using the real IP has a virus that's turned it into a bot-net or some such.

An example of this occurred during the past few days - several different IPs came in with a variety of UAs etc but ALL with a single proxy IP that placed the requester at a UK server farm in the range 88.208.193.nnn. This is not the first time this server range has attacked via proxies: it happened several months ago as well.
