Network World reports that Verizon says they have enough IPv4 Addresses. There are some estimates included on how many they might have. Stephan Langerholm, one of the TXv6TF Directors, is quoted.
Today, the free pool of IPv4 addresses unallocated by the IANA is starting to come to an end. The remaining /8s are 102/8, 103/8, 104/8, 179/8 and 185/8. Each of the RIRs will now get one of these as their final allocation from IANA. There will be an announcement about this situation on February 3rd. Check out this link for the live stream.
