Looking at my web-logs from yesterday I see a hit to my landing page from 136.22.133.6 which is:
136.22.133.0/24
AS36040
YouTube, LLC
User-agent was:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36
There was no referrer. It pulled every file that I would expect from an organic (human) hit to render the landing page, but it went no further than that.
That AS has a several widely-dispersed CIDR's but only about 10k IP's in total.
So what's up with that? Anyone else ever see this?
