This means that IPv6 can provide about ~340e+36 IP addresses. This new protocol uses 128-bit alphanumeric hexadecimal notation. Deployment commenced in the mid-2000s and since the internet users have grown exponentially, it is still ongoing. IPv6 is a new protocol that was introduced in 1998. Initially, it was more than enough but as internet adoption grew, we needed something better. The original Internet Protocol is IPv4 which uses a 32-bit numeric dot-decimal notation that only allows for around 4 billion IP addresses. Now, let's learn about the different versions of IP addresses: IPv4 IP addresses provide a way of doing so and form an essential part of how the internet works. The internet needs a way to differentiate between different computers, routers, and websites. They contain location information and make devices accessible for communication. In essence, IP addresses are the identifier that allows information to be sent between devices on a network. IP stands for "Internet Protocol", which is the set of rules governing the format of data sent via the internet or local network. IPĪn IP address is a unique address that identifies a device on the internet or a local network. ItĪlso makes it easier to reason about and manage architectural changes as the system evolves. To think from a high level as these decisions are very difficult to correct later.
One of the earliest decisions we can make when building a system. System design helps us define a solution that meets the business requirements. Us to think about everything, from infrastructure all the way down to the data and how it's stored. It requiresĪ systematic approach to building and engineering systems. Of your business or organization through coherent and efficient systems. System design is the process of defining the architecture, interfaces, and dataįor a system that satisfies specific requirements. Long polling, WebSockets, Server-Sent Events (SSE)īefore we start this course, let's talk about what even is system design.Command and Query Responsibility Segregation (CQRS).Please leave a ⭐ as motivation if this was helpful!
