Type in the prefix concerned.

The ‘Anti-abuse’ tab lists some well known blacklists, also 
historically.
The ‘ Database’ tab has registration and allocation history.
The ‘Routing’ tab has routing history.

In my experience all this goes a long way to get a good picture of the 
address space concerned.

It would be helpful if you told the list whether this would have warned 
this particular end-user had they or their consultants looked at it.
