[Dshield] IP Class C resolving to "localhost"

A user on our IRC network is joining and the IRC server is complaining
because the IP address resolves to localhost.

>nslookup 203.210.195.110
>Server:  kitsune.swcp.com
>Address:  198.59.115.2
>
>Name:    localhost
>Address:  203.210.195.110

Does anybody know a) why an ISP would want all IP addresses to resolve to
localhost, and b) if there could be any harm from an IP resolving to
localhost. I have never seen it before, and am not sure if it is some kind
of masking, or harmless.

Any help that you can provide would be appreciated.

Keith.
