There should be examples under the links I have added to the original comment. Unfortunately, I cannot give examples that I personally encountered (first, NDA, sorry, second, the ISPs would probably be very incensed to me), but browsing BGP collector sites would probably illuminate you, like this one (https://bgp.tools/prefix/41.189.185.0/24#whois, https://bgp.tools/prefix/41.189.185.0/24#dns) for caching Facebook and other Meta stuff, and this one (https://bgp.tools/prefix/2001:918:ffad::/48#whois) is for Akamai.
