uh-oh! North America Runs Completely Out of IPv4 Internet Addresses
Sep 26, 2015
Two months ago, THN reported about a similar announcement made by The American Registry for Internet Numbers (ARIN), which said that the agency is no longer able to produce IPv4 addresses in North America . Within a time frame of few months, ARIN, which handles Internet addresses in America, has announced the final exhaustion of their free pool of IPv4 addresses has reached zero... ...i.e. the availability of IPv4 (Internet Protocol version 4) addresses no more exists. Meanwhile, they are going to accept requests for IPv4, which will be approved via two ways: Wait List for Unmet IPv4 Requests - Join the waitlist for unmet requests in the hopes that a block of the desired size will be available in the future. IPv4 Transfer Market - Can be purchased from another organization that has more than it needs. So, in the future, IPv4 address space will be allocated to the approved requests on the Waiting List for Unmet Requests, if ARIN: receives any IPv4 address spac

North America Runs Out of IPv4 Addresses

The Internet is running out of IPv4 (Internet Protocol version 4) addresses — a computer's unique address on the Internet. It's just become harder to get IPv4 addresses. IPv4 Exhaustion Gets Real. Is this the end of IPv4 addresses? Finally, North America ran out of iPv4 addresses and officially exhausted its supply of IPv4 addresses, joining Asia, Europe, and Latin America. The American Registry for Internet Numbers (ARIN), which is responsible for handing out Internet addresses, has warned that it is unable to fulfil a request for the allocation of large blocks of IPv4 addresses due to IPv4 Exhaustion of available address pool. On Wednesday, ARIN activated an " IPv4 Unmet Requests Policy " for the first time and placed a waitlist for companies that request blocks of IP addresses for their services. According to the ARIN, ISPs are left with only three choices: They can either accept a smaller block (limited to 512 and 256 addresses) They can jo

Making Sense of Operational Technology Attacks: The Past, Present, and Future
Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.
