Does ENS use DNS?

I've been reading a lot about ENS recently, and it seems like it's a pretty innovative way to handle domain names in the blockchain space. But one thing that's been bugging me is the relationship between ENS and DNS. I understand that they're both used for domain name resolution, but I'm not sure how they differ or if ENS actually utilizes DNS in any way. So, does ENS use DNS? Or is it a completely separate system? I'm really curious to know how these two technologies interact, if they do at all.
