I've noticed a lot when using CDNs (streaming videos, files, etc) you download from a terrible-looking random-looking URL that looks something like vl-in-f95.1e100.net or a184-26-136-74.deploy.static.akamaitechnologies.com.

YouTube uses ones like https://r8---sn-5hne6ner.googlevideo.com/videoplayback

The thing is: what's the point of these and why are they used? How do DNS records propagate so quickly when generated?

Only akamaitechnologies.com or googlevideo.com is relevant for DNS, the rest is handled in that server's application. It's just another way to transfer a parameter.
