It can, but it tends to be a premium feature of specific DNS providers, not a global/by-default feature of DNS as efitz seems to be alluding to.

DNSimple supports it for example, but only on their "Professional" plan (and they call it "Regional Records") while others like Gandi don't support it at all.

If CDN providers are dealing with BGP you'd think they would also run their own DNS servers. I think you can do it with BIND views, from memory.
