    The Benefits and Risks of Leasing IPv4 Space

    With address prices rising, the reasons you may want to become a lessor are clear: extended predictable revenue. Leasing creates an opportunity to monetize IP addresses and sell an IP block for a higher price in the future versus in the current market – it allows the lessor to keep the IPv4 block in case of future need.

    What is IPv4 and Why Does it Matter?

    IPv4, or Internet Protocol version 4, is a set of rules that allows devices, like computers and phones, to exchange data on the Internet. Each device and domain connected to the Internet is assigned a unique number, called an IP address. These addresses ensure data is routed to the correct device.

    IPv4 vs IPv6: A full comparison

    Everything You Need to Know About IPv4 vs. IPv6

    The “IP” in IPv4 and IPv6 stands for Internet Protocol, which is a set of rules that determine how devices transmit data packets across the Internet. Internet Protocol also assigns a unique address to each device on the web. These addresses ensure data packets are routed to the correct device.

    IP Blocklist and Blocklist Removal

    Everyone hates spam. Even worse is malware—something that infects your computer and sends spam out to you and others or tries to hack into systems. In response to these problems, many people began to maintain lists recording who generates spam and malware.

    RPKI – today or tomorrow?

    Resource Public Key Infrastructure (RPKI) is a mouthful. Essentially, RPKI ensures that the network saying, “We are the place to send traffic for network A.B.C.D” really is the right place.

    Buying and Selling IPv4 Addresses – Part II

    As previously discussed in part one of this series, IPv6 hasn’t quite made the giant splash throughout the enterprise landscape that many expected. Now, don’t get me wrong, IPv6 still plays a major role in the IT space. In the world of telecommunications, IPv6 is a key enabler of next-generation technologies and communication strategies, as carrier networks, ISPs, and mobile networks roll out the new protocol across their networks.

    Buying & Selling IPv4 Addresses – Part I

    As we progress further into the digital age, new technologies are the driving forces behind IoT, Big Data, and enterprise cloud computing. The growth in these areas comes principally from massive economies of scale in storage, bandwidth, chipset manufacturing and other inputs.

    IP Address Reputation

    Among the problems created by the early design of the internet was the limited supply of IP addresses. To help solve this problem, markets have evolved, creating redistribution paths for “surplus” addresses. To read about the transfer of these assets, the changes taking place and to get some idea of the possible future…

    WHAT IS CIDR?

    What is CIDR

    Pronounced “cider,” CIDR stands for Classless Inter-Domain Routing. CIDR is a method for summarizing IP addresses. Its original goal was to slow the exhaustion of IPv4 addresses and help extend the life of IPv4. It also improved the efficiency of IP address assignments, and overall significantly improved the availability.

    IPv4 Market and IPv6 Deployment

    Preparing for this session has provided an opportunity to research how the IPv4 address market has affected the deployment of IPv6. To begin, we look at the total addresses transferred and the number of addresses transferred over time.

    What is an ASN Broker?

    One reason the Internet is so robust is that authority is decentralized: every network is run independently. Each network operator (whether a major cable or mobile company or community WISP (wireless ISP)) decides who they will connect to. As those networks connect, they tell each other what IP addresses they know how to reach.
