That's called "hosting". There only thing "wrong" with it is they aren't split across two - which is generally recommended operationally. Did you customer say why they thought that was a problem i.e. "can't reach" "won't resolve" etc.? ARIN says you own that IP space so I'm not sure what you are trying to tell us...

I've just been hired to fix problems at a small ISP. One of their customers has listed several nameservers with a single IP.
I didn't know this was possible. I thought there was a 1 to 1 relationship with nameserver names/addresses. I'm trying to figure out if this is or will be a problem.
Any input would be greatly appreciated. Bob Martin
