alt Hacker NewsI didn't check thoroughly, but the first one I happened to grep out was not on that list:
"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Amazonbot/0.1; +https://developer.amazon.com/support/amazonbot) Chrome/119.0.6045.214 Safari/537.36"
"x-forwarded-for":"44.210.204.255" "x-real-ip":"44.210.204.255"
This is a bit outside my area of expertise, so I don't know how reliable these x-forwarded-for and x-real-ip are.
One of the places to look it up would be bgp.tools [1] The IP is purported to belong to Amazon and the ASN has some interesting tags. [2] Any form of forwarded-for can be spoofed and should only be considered from expected up-stream proxies such as a CDN and they should have a CDN specific IP header that would be listed in their documentation. Typically the first column in access logs will be the REMOTE_ADDR which is the actual network connection but if using a CDN that would be the CDN IP.
If a CDN does not have an option to block cloud and Tor CIDR blocks then that should be a feature request.
44.210.204.255 is included in 44.192.0.0/10 which is listed in the AWS CIDR ranges. Use one of the online subnet calculators to find IP ranges of CIDR blocks. This is likely a Tor exit node.
Blocking the CIDR blocks I listed in the thread would have included this node as well. Here [3] are a few shell functions for getting some of the cloud CIDR blocks. I must have been inebriated when I wrote those. This site may not be reachable during blood moons or when the nanosecond is divisible by zero.
Here [4a][4b] are a couple decent subnet calculators. There are some command line tools for playing with CIDR blocks and IP addresses to see if an IP is included in a CIDR block but this varies by Linux distribution so perhaps look for a generic python script.
To get a list of Tor exit nodes to blackhole route, look at [5]. This updates often. Just clone the entire repo. Unless your site is related to government dissent or anonymous porn then most traffic from Tor exit nodes will likely just be bots and thus riff-raff.
Seconds after I linked realhackers bots showed up and got a zero byte response. Poor lil HN servers must get a lot of trash non stop. I hope I get some delicious bots today.
