The supply of IP version 4 internet addresses could be used up this week. ComputerWorld reports, the Asia Pacific Network Internet Center is eligible to request two of the remaining seven large blocks of IPv4 addresses. If its does, it would trigger a policy of the Internet Assigned Numbers Authority. The policy requires IANA to hand out the last five blocks to five regional registries. The move would end further availability of IPv4 addresses. An IANA spokesman says IPv4 could disappear by the end of the week. Federal agencies are supposed to have made the switch to IPv6, which has unlimited addresses. But several deadlines have come and gone.
