Loop back for DNS on clients

I work at an outsourced helpdesk and occasionally I see 127.0.0.1 input as DNS. I can understand why you would want to do that on the DNS server itself but why on a client pc? Are there any advantages to having a client use its host file for DNS? Doesn’t it cause more administrative effort? Wouldn’t ARP and mapping drives take care of finding files and servers within the network even if it is a home group rather than being on a domain? Thanks in advance as nobody I’ve asked seems to know.
