I’m pretty certain that DNS is all about domain name resolution, but I guess I should double-check my notes just in case!

I’m a bit confused because I feel like DNS might relate to email somehow, but I’m leaning towards domain name resolution being the right answer.

I think the DNS protocol is mainly about resolving domain names, but I’m not 100% sure if that’s the only function it serves.
