Exactly, DNS is specifically for hostname to IP address mapping.

That's true Werner, but DHCP is not for mapping hostnames to IP addresses.

But what about DHCP? Doesn't it assign IP addresses too?

That's right, Annmarie. DNS is like the phone book of the internet, matching names to numbers.

DNS is essential for translating human-readable domain names into IP addresses that computers use to communicate.

I'm not sure about this one. Can someone explain why DNS is the correct answer?

I was about to choose DHCP too, Effie. But DNS does seem like the more appropriate answer here. Though I have to admit, I'm a bit rusty on my networking protocols.

Hmm, I was thinking it might be DHCP, since that's the protocol that assigns IP addresses to devices on a network. But now that you both mention DNS, that makes more sense.

Yeah, I agree with Salena. DNS is the distributed database that handles that kind of hostname-to-IP mapping. The other options don't really seem to fit the question.

This question seems a bit tricky. I'm not entirely sure about the difference between all these protocols, but I think DNS is the one that maps hostnames to IP addresses.
