Because new addresses are limited, many companies now choose to buy IP blocks from others instead of waiting for fresh allocations. Buying IP blocks has become part of modern network planning. A company that buys addresses can support itsRead more

Each time you open a web page or send an email, that number helps data find its way. The act of giving out these numbers is called IP allocation. It may look like a simple job, but inRead more
Subnetting is a key concept in the field of IP network management. Understanding the way subnetting impacts IP allocation is helpful for optimising network performance. It is also helpful for improving network security. Simplified Network Management Managing a large network is quite daunting. But subnetting changes this situation. It makes the management of large networks more manageable. The way it does this is by dividing the large network. TheRead more
DHCP uses a four-step process (Discover, Offer, Request, Acknowledge) to lease IPs automatically from a pool. It supports dynamic, automatic, and manual (reserved) allocation to avoid address conflicts and ease network management. What is DHCP and why it matters The service called Dynamic Host Configuration Protocol (DHCP) automatically assigns the IP addresses and other network information to devices. Without the DHCP, network have to manually configure the every deviceRead more
The Global IPv4 Shortage and Its Far-Reaching Effects The Internet uses numbers called Internet Protocol addresses. Each device needs one number. A computer needs one. A phone needs one. A server needs one. A sensor needs one. These numbers allow devices to send and get data. The system most networks still use is called Internet Protocol version 4. People call it IPv4. It was created many years ago whenRead more
