A simple guide that shows how ISPs get IP addresses and give them to users. It also looks at the steps, the problems, and the rules behind it. ISPs get IP address blocks from RIRs. They give these to users by using DHCP, fixed IPs, or shared IPs through NAT. IANA and the RIRs help control the system. They make sure the addresses are used well and not repeated.Read more
IP address allocation is giving unique numbers to devices on a network. IANA gives large blocks of IP addresses to regional groups. These groups give them to smaller providers or companies. The goal is to make sure IP addresses are used fairly. This system has been in place for many years. It helps prevent waste and keeps the internet organized.Once the request is approved, the company receives a blockRead more
Introduction to IP delegation The correct way to give out and manage Internet Protocol (IP) addresses is important for keeping a network running well. IP authorisation is a main part of this system. It means passing down blocks of IP addresses from global groups to smaller groups like local or regional ones. This helps use IP addresses in a better and more organised way. As more companies dependRead more
Primary Use CasesIPsec is widely used for VPNs, site-to-site tunnels, and full-network protection in corporate settings. HTTPS is best suited for websites, online services, and API endpoints, where user trust and browser compatibility are key concerns. When might you use both? While IPsec and HTTPS are generally used independently—each addressing different layers of the network stack—there are specific scenarios where organisations may choose to deploy both protocols simultaneously.

What does leasing IP addresses mean for global businesses? Instead of buying IPv4 or IPv6 blocks altogether, leasing entails renting them from a supplier. This provides quick access to address space across several areas, which is essential for multinational corporations given the shortage of IPv4. Through leasing, expansions and short-term requirements can be easily met by transferring the cost from a significant capital investment to a manageable operational outlay.Read more
