ICMP sounds familiar, but I think that's more about error messages and not resolving host names.

I'm not entirely sure, but I remember ARP is related to local network addressing, not host name resolution.

I think the answer is DNS because it translates domain names into IP addresses, right?

I’m a bit confused between DNS and ICMP. I know ICMP is for error messages, but I can’t recall if it has anything to do with name resolution.

I feel like I’ve seen a question like this before, and DNS was definitely the answer. It makes sense for host name resolution.

I remember studying ARP, but that’s more about IP to MAC address resolution, right? So it must be DNS.

I think it's DNS because it translates domain names to IP addresses, but I'm not 100% sure.
