> Background
> During the RIPE 48 meeting in Amsterdam, a proposal was presented by  
> APNIC
> to replace the fixed utilisation criteria of 80% to request additional  
> IPv4
> addresses blocks, by a criteria based on "AD ratio" value. This ratio  
> value
> corresponds to a logarithmic scale and corresponds to a percentage
> utilisation, which decreases as the size of the address space grows.

> The decision was made to take the discussion to the RIPE Address-policy
> working group mailing list and to ask for some feed back from the  
> community.
> As most European Telecommunications Network Operators' Association  
> 1(ETNO)
> members are large or extra-large Local Internet Registries in Europe,
> representing an important part of these categories in the RIPE region,  
> this
> proposal was considered and analysed with attention.
>
> Findings
> 1- This proposal fairly takes into account addressing hierarchies used  
> in
> large and extra-large registries and introduces a useful level of
> flexibility for those registries.
> 2- The Local Internet Registries using the 80% criteria may continue  
> to do
> so and will not be impacted by the new policy.
> 3- Complicated calculation or administrative burden should be easily  
> avoided
> to registries choosing this method using simple chart or software  
> through
> LIR portal.
> 4- As analysed by APNIC, the impact on address consumption is limited  
> to a
> maximum around 20% and can be easily controlled and monitored using a  
> rather
> conservative approach (AD ratio of 0.966).
> 5- This impact can be partly counterbalanced by reducing the number of  
> small
> and extra-small registries whose existence is only justified by  
> management
> overhead of large registries with current 80% criteria, and has a  
> positive
> impact on address aggregation.
> 6- No additional impact on registrations is seen in RIPE region, as
> infrastructure assignments are already registered in the database.
>
> Conclusion
> ETNO strongly supports this proposal and suggest selecting a  
> conservative AD
> ratio value of 0.966.
>
> ETNO also suggest to the RIRs to monitor the use of this facility and  
> its
> impact on address consumption, and periodically report on it to the
> addressing community.
