The Evolution and Implications of IPv4 Mapped IPv6 Addresses
Discover IPv4 mapped IPv6 addresses: bridging the gap between protocols, enabling smooth communication & gradual migration. Advantages & implications explained. The transformative impact of the internet on modern society cannot be overstated. From connecting people across the globe to enabling a myriad of digital services, the Internet has become an integral part of our daily lives. As the internet has grown, so has the need for unique IP addresses to identify and communicate with devices. This led to the development of Internet Protocol version 4 (IPv4), which, over time, revealed its limitations in accommodating the exponential growth of internet-connected devices. To address this challenge, Internet Protocol version 6 (IPv6) was introduced, offering a significantly larger address space. However, transitioning from[…]

Is Buying IPv4 Address a Good Option? Understanding the IPv4 Market
The internet has experienced exponential growth since its inception, connecting billions of devices and individuals worldwide. The cornerstone of this connectivity is the Internet Protocol (IP) address, which serves as a unique identifier for every device connected to the Internet. However, the widespread adoption of the Internet Protocol version 4 (IPv4) over the past few decades has led to an unforeseen problem: IPv4 address exhaustion. This issue has created a unique marketplace where organizations can buy and sell IPv4 addresses to meet their growing demand for IP addresses. In this article, we will explore the complexities of the IPv4 market, weigh the pros and cons of buying IPv4 addresses, and provide guidance for organizations navigating this dynamic landscape. The IPv4[…]

Understanding the Differences between TCP/IP and OSI Models
TCP and IP are the two main network protocols or communications standards of the internet. Where TCP defines how different applications can communicate over reliable channels across a network, IP regulates how devices connected to the internet can transmit and receive data over the network or an interconnected set of networks. In other words, IP defines routing and addressing while TCP defines how the connected peripherals can communicate across the IP-mediated link without any data loss. The OSI or Open Systems Interconnection model, on the contrary, defines how the different tasks related to the network communication can be segregated across multiple layers of software and hardware components. It was developed by the International Organization for Standardization (ISO) as the ISO/IEC[…]

Is a Dedicated IP Address Mandatory to Install an SSL Certificate?
An SSL certificate works by encrypting the data sent and received from/by a user’s device to/from a website. This gives users a secure channel to enter the necessary information on the browser and communicate with the webserver. Having an SSL certificate is also seen to help the website ranking and lead to better visibility on search engine result pages. Earlier, installing an SSL certificate was possible only on dedicated IP addresses. Yet as the importance of a secure internet grew, developments in technology created a way for shared IP addresses to use SSL certificates as well. This is possible through the Server Name Indicator or SNI, which allows a webserver to create different virtual host environments and host multiple SSL[…]

IPV4 Opportunity – Infographic
A considerable number of unused IPv4 addresses exists in organizations around the world. With the IPv4 resources running out, trading these between private entities emerged as the ideal solution for their depletion. This is where IPv4 brokers come in. Third-parties like IPv4Mall act as middlemen between those entities having a surplus stock of these resources and the ones who are seeking them. The brokers make the processes of selling and buying the addresses easier. In a way, they are grateful for the fact that there exist unused addresses, and consequently, a secondary market for IPv4 addresses. The following infographic puts all of the above into context.

Tips to Remove your IPv4 Address from a Blacklist
IPv4 address blacklisting is done to control spam and prevent malicious activities. Every blacklist has its own set of criteria for blacklisting IP addresses of email spammers, which could be based on technical factors, ISP policy, and evidence-based. Technical blacklisting usually happens due to mail servers configuration issues, such as improper reverse DNS records and banner greetings, and mail servers operating within a range of suspicious IPv4 address blocks. ISP policy-based blacklisting is done when the receiving server decides not to accept emails from specific countries or ISPs, which are known for not following unsubscribe requests properly. Evidence-based blacklisting refers to those cases wherein the server has reliable proof to block an IPv4 address block because it has been involved[…]

The Underlying Benefits of IP Address Management
IP address management refers to the administration of DHCP and DNS, which assign and resolve IPv4 addresses to a machine in the network. IP address management can be termed as planning how to use the IPv4 addresses in a network, as well as tracking and managing them. Network services like DNS and DHCP work concurrently to perform these duties, and IP address management can enhance their function for the better. IPv4 addresses form a vital part of any network and managing them can be a bit difficult without a proper IP address management strategy. As the number of IP addresses in your network grows, assigned for different databases, applications, and microservices, it can be very tricky for network administrators to[…]
