Situation

6.2 IPv4 Address Space currently allocated to the RIRs RIPE has 7 x /8’s (62, 193, 194, 195, 212, 213, 217) ARIN has13 x /8’s ( 63, 64, 65, 66, 199, 200, 204, 205, 206, 207, 208, 209, 216) APNIC has 6 x /8’s (61, 202, 203, 210, 211, 218)

IANA still has many address blocks reserved and available for allocation to RIRs, namely:

1, 2, 5, 7, 23, 27, 31, 36, 37, 39, 41, 42, 49, 50, 58, 59, 60, 67-95, 96-126, 197, 201, 219-223, i.e. 84 /8s. In addition to this, the former "Class B" space is completely free from 173/8 to 191/8, i.e. 19 /8s. This makes a total of 103 /8s available for allocation to the RIRs.

Setting protocol

1999, the IETF IPv6 Working Group announced that the protocol was finished and ready for implementation.

Sept. 2000, Japan advocated deployment of IPv6 Feb. 2001, South Korea followed April 2001, European Commission called for its quick

adoption United States has shown little enthusiasm for

implementation of the next-generation Internet.
