Unfortunately, that doesn't necessarily mean a stranger on the Internet isn't the actual assignee. A means to definitively prove "ownership" from a technical angle would be great.

Hi Sean,

There is a definitive technical means. It's called contact the POC
published in WHOIS by the RIR and ask. It isn't flawless and you don't
have to like it, but there it is.

If you contacted the POC and the POC replied stop, you stop. If the
POC was hijacked at the RIR, that's between your customer and the RIR.
The RIR has a standard process and an expert team for dealing with
these situations. It's their job.
