PV6 is considered an alternative to the traditional 32-bit address space on the ipv4--Internet, which is used to solve the problem of the impending exhaustion of the existing IPV4 address space. However, since a large number of hosts and devices are connected to the Internet with IPV4, it is almost impossible to switch them all overnight to IPv6. Many IPv4 to IPv6 conversion mechanisms (e.g., dual protocol

[IPv6] Detailed description of ISATAP tunnel technologyI. Basic ConceptsISATAP (Intra-SiteAutomatic Tunnel Addressing Protocol)ISATAP is an IPv6 transition mechanism that is easy to deploy and use. In an IPv4 network, we can easily deploy ISATAP. First, you need a V4/V6 dual-stack PC. Then, you need a vro that supports ISATAP, the ISATAP router can be anywhere in the network, as long as the PC can ping it (

Why do we need to deploy IPV6? · Limitations of IPv4: 1. Limitations of address space: the IP address space crisis has been around for a long time and is the main driving force for IPv6 upgrade. 2. Security: IPv4 has no security at the network layer. Security is always considered to be the responsibility of a layer above the network layer. 3. Automatic Configuration: the configuration of IPv4 nodes is compl

Article title: IPv6 applications in Linux networks. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. IPv6 (Internet Protocol Version 6) is a next-generation network agreement that replaces IPv4. it has many new features and functions. As the next-generation Internet conne

[Editor's note] the IPv4 address is exhausted and IPv6 is to be promoted, but it has been delayed. In this case, do not let it disturb our system before it is ready. IPv6IPv6 is the next version of IPv4 in the addressing scheme. It is used to assign a digital address to the domain name. IPv6 supports more addresses than IPv4. However, it has not been widely supported and is still being accepted. Ubuntu enab

The network is called a network because of its large system and there are no isolated islands. With the use of IPv6, there is a small island in the network. In order to connect networks of the two protocol versions, we need to use the IPv4/IPv6 Tunneling mechanism to accomplish this arduous task. How can we achieve this? Next we will explain in detail the tunneling technology. Tunneling Technology Before an

1. Introduction IP version 6th (IPV6) is a new version of the Internet protocol after IP version 4th (IPV4) [RFC-791]. The changes from IPV4 to IPV6 are mainly concentrated in the following areas: expansion of address capacityIPV6 increases the size of the IP address from 32 bits to 128 bits to support more address levels, larger numbers of nodes, and simpler address autoconfiguration. Scalability improveme

As early as the formation of IPV6 technology, people have begun to study and demonstrate the transition, coexistence, and interconnectivity of IPv4/IPV6 networks, it focuses more on how to smoothly migrate from a traditional IPv4 network to the ultimate IPV6 network at the basic network layer. When IPV6 applications ar

With the continuous development of internet technology, the traditional IPV4 address can not meet the needs of users. The new generation of IPV6 protocol is increasingly widely accepted and used, and more and more software systems are required to support IPV6 network protocol. However, the existing network environment support to IPV6 is still very limited, which

In order to better integrate IPv4 and IPv6 protocols, we have adopted many technologies for intercommunication between the two networks. First, let's introduce the tunneling technology. And some related transitional technologies. Tunneling Technology Before an IPv6 network completely replaces an IPv4 network, some access network technologies first have an IPv6 pr

The global IPv4 address is about to run out. There are two ways to address shortage: one is to introduce IPv6 to fundamentally solve the address problem, and the other is to solve the problem from the IPv4 layer. Insufficient IPv4 address space is the driving force behind migration, but the two protocols are not compatible with each other, which is the biggest reason for the inability to quickly switch. Therefore, beacon communication believes that IP
