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 --Heather On Wed, Aug 15, 2012 at 3:42 PM, Tobias Knecht <tk@abusix.com> wrote:
Hi everybody,
When nothing else works, blocking a range is what remains. Yes, blocking could be made better, for example some feedback from registries when a block has been reallocated might be of value. This info could be announced in by RIPE et.al. so blocklist operators may pick up this info.
This is a great idea and an option that has been discussed at other institutions already. I will put this on my list for future discussion and I bet this would really help a lot if blacklists are willed to use the offered information.
Thanks,
Tobias
