Current IPv4 Delegation Policy and Practice in each region• APNIC: Maximum /22 from final /8 (103/8). Requests for

additional /22 from recovered pool will be put into the waiting list.

• RIPE NCC: Maximum /22 from the final /8 pool for each member.

• ARIN has run out their IPv4 free pool. All requests will be put into a waiting list.

• LACNIC: Maximum /22 for each member every 6 months

• AFRINIC: Expect to hit their final /8 early next year.

Which RIR allows IPv4 inter-RIR Transfers?• APNIC, ARIN and RIPE NCC implemented inter-RIR IPv4

transfer policy.

• LACNIC and AFRINIC don’t have inter-RIR transfers policy.

IPv6 Allocations (RIRS to LIRs/ISPs)How many allocations have been made by each RIR by year?

Current IPv6 Delegation Policy and Practice• It is very easy to request IPv6 from all RIR

• APNIC members can receive their IPv6 by one-click via MyAPNIC

• CNNIC members can request their IPv6 from CNNIC easily

ASN Assignments (RIRs to customers)How many ASNs has each RIR assigned by year?


4-Byte ASN Assignments How many 4-byte ASNs has each RIR assigned by year?

Current ASN Delegation Policy and Practice• Since 2007, RIRs started to delegate 4-byte AS Numbers

• 2-byte AS Number is running out

• All RIRs assign 4-byte AS Numbers by default now

• If you request for a 2-byte AS Number, you need to prove either your equipment or upstream does not support 4-byte AS Number
