Why did 04 2166 9216 hang up when I answered?

Is 0421669216 a scam or just a nuisance call?
Based on the report received, 04 2166 9216 appears to be a nuisance caller rather than an active scam attempt. The caller did not make any claims, requests, or threats - they simply hung up. However, this type of behaviour can be a precursor to scam contact, so it's worth blocking the number and staying alert.
Should I block 04 2166 9216?
If 0421669216 calls you and hangs up, it's reasonable to block it immediately. The contributor who reported 04 2166 9216 noted the behaviour seemed dodgy, and there's no legitimate reason for a caller to hang up without leaving a message or identifying themselves.

Could 04 2166 9216 be a legitimate business?
It's possible, but legitimate businesses typically leave voicemail messages or identify themselves when you answer.
