Overview of Policy Proposals

Policy SIG

Wednesday 31 August 2011


Proposals under discussion
Proposals under Discussion

  • prop-096: Maintaining demonstrated needs requirement in transfer policy after the final /8 phase

  • prop-098: Optimizing IPv6 allocation strategies (simplified)

  • prop-099: IPv6 Reservation for Large Networks

  • prop-100: National IP Address Plan - Allocation of country-wide IP address blocks


Prop 096 maintaining demonstrated needs requirement in transfer policy after the final 8 phase
prop-096 Maintaining demonstrated needs requirement in transfer policy after the final /8 phase

Problems this proposal aims to address:

  • APNIC is the only RIR that does not require a demonstrated need for transfers.

  • Other RIRs are reluctant to recognize any inter-RIR transfer policy with APNIC.


Prop 096 maintaining demonstrated needs requirement in transfer policy after the final 8 phase1
prop-096 Maintaining demonstrated needs requirement in transfer policy after the final /8 phase

Proposed solution:

  • It is proposed that recipients of transfers be required to justify their need for IPv4 address space.


Prop 098 optimizing ipv6 allocation strategies simplified
prop-098 Optimizing IPv6 allocation strategies (simplified) transfer policy after the final /8 phase

Problems this proposal aims to address:

  • LIRs feel they must fit their entire subscriber base in a single /32.

  • Network outages caused by bit math errors. This will lead to disaggregation.

  • The HD ratio leaves much to be desired as an address administration tool.


Prop 098 optimizing ipv6 allocation strategies simplified1
prop-098 Optimizing IPv6 allocation strategies (simplified) transfer policy after the final /8 phase

Proposed solution:

  • Utilization be measured in ‘Provider Allocation Units’ - smallest reassignment unit

    • 75% or more utilization, or

    • One or more facilities has reached a 90% utilization and no blocks available to expand


Prop 098 optimizing ipv6 allocation strategies simplified2
prop-098 Optimizing IPv6 allocation strategies (simplified) transfer policy after the final /8 phase

Proposed solution:

  • Allow LIRs to request nibble-aligned blocks of any size greater than or equal to /36

    • Default minimum is /32

    • Maximum to accommodate 5 years

    • Subordinate LIR block count as fully utilized


Prop 098 optimizing ipv6 allocation strategies simplified3
prop-098 Optimizing IPv6 allocation strategies (simplified) transfer policy after the final /8 phase

Proposed solution:

  • Subsequent allocations expand to the next nibble – existing allocation can be re-sized

  • Allocation shall not exceed a /16, but, a provider may receive multiple /16s to meet justified needs

    • LIR is ‘encouraged’ to vacate their old allocations


Prop 099 ipv6 reservation for large network
prop-099 IPv6 Reservation for Large Network transfer policy after the final /8 phase

Problems this proposal aims to address:

  • Slow start policy allocates /32 then reduces the bit mask one bit at a time

  • This causes fragmentation and complexity in large networks with POPs growing at different rates.

  • IPv6 Policy does not take into account long-term (up to 10 years) future growth.  


Prop 099 ipv6 reservation for large network1
prop-099 IPv6 Reservation for Large Network transfer policy after the final /8 phase

Proposed solution:

  • Multiple prefix request

    • Separately justified (Prop-083)

  • Subsequent allocations made within a reserved space as:

    • Extensions to existing prefixes and/or

    • New prefixes


Prop 099 ipv6 reservation for large network2
prop-099 IPv6 Reservation for Large Network transfer policy after the final /8 phase

Proposed solution:

  • Reservation request for projected network growth up to 10 years

    • Long-term network plans

    • Environmental factors


Prop 099 ipv6 reservation for large network3
prop-099 IPv6 Reservation for Large Network transfer policy after the final /8 phase

Proposed solution:

  • Reservation expires after 2 years unless re-justified

    • Allocated prefixes registered in whois

    • Reservation documented separately


Prop 100 national ip address plan allocation of country wide ip address blocks
prop-100 National IP Address Plan - Allocation of country-wide IP address blocks

Problems this proposal aims to address:

  • IPv6 is allocated in the same way IPv4

    • To organizations rather than geographies

    • Based on 1 year demonstrated need

  • This will cause the same problems in IPv6 as we have in IPv4

    • Fragmentation

    • LEA difficulty in tracking down abusers


Prop 100 national ip address plan allocation of country wide ip address blocks1
prop-100 National IP Address Plan - Allocation of country-wide IP address blocks

Proposed solution:

  • One big block of IPv6 Addresses (e.g. /17) reserved for India

    • Size to be based on future requirements for next 20 years at least

    • Allocated to Indian NIR (once operational)

  • Block used for all TSPs/ISPs and other organizations


Thank you
Thank you country-wide IP address blocks
