반응형 전체 글30 IP Address v6 - Expression, Advantages and Disadvantages In this session, we will look at the expression, characteristics, advantages, and disadvantages of IPv6, which will replace IPv4. I wonder when our IT will be able to use it freely, but let's study it before that time comes. 1. IP Address v6 Representation IPv4 Address expression currently in use 32Bit = 4.2 billion IPv6 Address Space 128 Bit = 4.2 billion × 4.2 billion × 4.2 billion × 4.2.. 2024. 5. 8. Understanding the Cloud, Five Features This time, the cloud that we've been listening to these days. Let's take a look at what this cloud is and what its characteristics, its strengths and weaknesses are. 1. What is the cloud ? First of all, cloud means "cloud," which means space that can be stored on a central computer through the Internet, not inside the computer that you worked on when storing computer files. For example, if a.. 2024. 4. 25. VRRP Concepts - Gateway Redundancy In this session, we will learn about VRRP, gateway redundancy in the network. It's a feature that's usually used to redundancy two backbone switches. It's not as easy as you think if you can do redundancy work on the switch, it's going to be at some level, so watch carefully. 1. VRRP (Virtual Redundancy Routing Protocol) : VRRP requires a Layer 3 switch or router that acts as a gateway to commun.. 2024. 4. 23. Learn more about Subnetting & Supernetting In this session, we will learn about the concept and calculation method of subnetting and super netting. Understanding subnet masks is the most important point to understand IP addresses clearly. It's literally a sub. You can think of it as a mask that you put on to make a network through some processing, not the main. In other words, once we're assigned an IP address, we don't usually use it as.. 2024. 4. 22. IP address v4 & v6 - Easy and quick to understand In this session, we will learn more about IP address v4/IPv6. The identifier used by the IP layer in the TCP/IP protocol collection to distinguish each device connected to the Internet is called an Internet address or IP Address. 1. IP Address v4 - Size: 32 Bit (23232 = approximately 4.3 billion) - All depleted in 2011. - Class A, B, C, D, E A Class (0 to 127): Common bit class with the first bi.. 2024. 4. 15. IP Address Concept and Public, Private IP Description This time, we will learn about IP address, which is the foundation of network communication. First, we will learn about IPv4, and we will deal with IPv6 in detail later. 1. IP Address The only way to distinguish all devices connected to the Internet is to communicate globally between all devices, so the IP Address was created. IP Address is the only address that distinguishes the individual host.. 2024. 4. 10. What is Domain Name System (DNS)? In this session, we will learn about the concept of Domain Name System (DNS), why it is used, components, and operating principles. 1. What is DNS? When we use the Internet to search, surf the web, or e-mail, we enter the domain name (www. Naver.com) in the address bar of the web browser and access Naver. In other words, the actual naver.com server communicates with an IP address composed of num.. 2024. 4. 8. 3 ways of communicating with protocol concepts (uni/multi/broadcast) In this session, we're going to understand the exact concept of what protocols are talking about in the network, and learn about three ways of communication. Unicast/multicast/broadcast Everyone must have heard of this method a lot, but for those who don't know what it means, this is also the basic, so please be aware of it. 1. What is a protocol? The dictionary meaning of the protocol is "rules.. 2024. 3. 30. 이전 1 2 3 4 다음 반응형
