I say never because the RIR system has not failed. Its model has been
successful albeit with hicups yet it has stood the taste of time and the
last thing we want as a community is to attempt on inacting chaos as the
new normal.

The community has long permitted ISPs to authorize a

We are all aware that ISPs are generally LIRs and as such, their downstream
endusers/customers often time get assigned small blocks like /24 based on
need ontop of the connectivity services they are provided by the ISP.

When ISP customers churn, most ISP recover the assigned block back into the
LIR inventory for re-assigning to new customers and this is a known

Very few and those IPs were transferred to those customers who then became
resource members through the RIR process.

Unused address ought to be returned back to the RIR inventory for further

Good...... and the RIR system and only the RIR must handle the management
and distribution based on need of IP resources and not a 3rd party entity
that the community does not even recognize.

IP Leasing undermines the foundation of the system that has served the
Internet community so well.

Any endorsement of such a practise will be setting a very dangerous
presidence if we attempt to ignore order in favour of an unregulated
practise and greed. There has to be a limit, a demarcation, as to how
internet number resources are managed and distributed.
