[anti-abuse-wg] Hold time for abused address space - DNSChanger IP's reallocated

We've kind of veered away from the topic/questions I had about
reallocating actively abused address space.. but..

I thought it was odd that I could not find a registration date in the
RIPE db - at the time I thought I just couldn't find it, maybe it's
not actually published?

In the ARIN region both registration date and last updated on, are
provided - something similar might be helpful?

ARIN example:
NetRange	63.72.0.0 - 63.72.3.255
CIDR	63.72.0.0/22
Name	UU-63-72
Handle	NET-63-72-0-0-1
Parent	UUNET63 (NET-63-64-0-0-1)
Net Type	Reassigned
Origin AS	
Customer	Disney Regional Entertainment (C00576500)
Registration Date	1999-06-02
Last Updated	2003-05-30
