Why the advances? • IPv4 space ”run out” years ago (IANA/PTI has no more /8s to dole out to the RIRs) • ARIN inventory is empty. • APNIC and LACNIC inventory is near empty. • RIPE and AFRINIC projected runout is soon (or not, depending on who you ask). Available IPv4 /8s at Each RIR AFRINIC APNIC ARIN LACNIC RIPE NCC 0.6 0.45 0.44 0.3 0.26 0.11 0.00 0 Source: https://ipv4.potaroo.net So? • AFRINIC is in “exhaustion” phase – where there are restrictions (through the PDP) on maximum v4 space an entity can acquire. (each RIR has different restrictions). • AFRINIC is using the “Soft Landing” policy to distribute v4 space. We are now in Exhaustion Phase 1, where max = /13 • ARIN, RIPE NCC and APNIC introduced a process through which IPv4 space can be transferred between themselves (Inter RIR transfers), through their respective PDPs.
