How many actual "human" ipsBuried somewhere upthread is the detail that the final /11 within 43/8, i.e. 43.224-255, may include human ISPs. And even if your target audience is not likely to include {Asian country of your choice}, you probably don't want to exclude Australia and New Zealand. Heck, they might be buying something from a US-based business to ship to their relatives in the US.
Look at FireFox, Chrome, Edge. <== Request HeadersOut of millions of Sec-blahblah headers, I found only a hundred or so containing \" (that is, escaped quotation mark in addition to the usual quotation used in this header) or ^, so I'm confident calling them bogus. But on the other hand they are so rare, it's not currently worth blocking on those grounds alone.
