Mulitple DNS A records

I’ve just started at a company, and in their DNS they have several IP’s that have multiple A records associated to them. I’ve not seen this before, and wondered if they should have CNAMEs instead? I can see the reason for multiple A records with the same label against *different* IP’s, but not the other way round.

eg.
A Records – IP
Server1 – 192.168.0.1
FileServer – 192.168.0.1

Any help is much appreciated.
