In this special period of network transformation. We often explore the transition between IPv4 and IPv6. We have talked a lot about the conversion technologies related to them. Now we are introducing you to a transitional technology, that is, translation strategies. What are the translation strategies of
What are the differences between IPv4 and IPv6? We can understand the difference between IPv4 and IPv6 through the following, we will appear IPv4 and IPv6 when we connect the wireless network, then where is the difference between
The Next Generation Network (NGN) is an open network oriented to unconnected IP networks. IPv4 runs successfully on the Internet. With the development of the Internet, IPv4 faces many problems, such as lack of Address Resources, node security, and mobility. This is what IPv6 can solve. However, the transition from IPv4
Network Layer 2 (IPv4 and IPv6 addresses and related protocols) IP (internet protocol) protocol is the core protocol of the TCP/IP protocol family and the network layer of the internet. The current version number is 4, also known as IPv4. The next generation IP protocol version number is 6, that is, IPv6. As described
other parts, so it is very easy to implement. However, tunnel technology cannot directly communicate with IPv4 hosts and IPv6 hosts.
Network Address Translation/protocol conversion technology
The Network Address Translation/protocol conversion technology is combined with the SIIT protocol conversion, the traditional
, and hosts within the private network cannot communicate directly with the public network. But through the network address translation, they can do the latter.And then what. Then represents the IPV4 of the past, just like the simple occupation of operations, will soon be forgotten. Just a matter of time, so in the IPv4 world, we are 32-bit, this 32 is like the s
The two major problems facing internet basic technology IPv4 are address resource depletion and backbone router route table explosion. These two problems are the defects of IPv4 protocol, only a large modification can be done. After years of discussion and comparison and trade-offs of various solutions, the next-generation IP protocol has been basically developed and assigned version 6, called
IPV6 is the abbreviation for "Internet Protocol version 6", which is the next generation IP protocol designed by the IETF to replace the current version of the IP protocol-ipv4-.
At present we use second-generation Internet IPV4 technology, the core technology belongs to the United States. Its biggest problem is that the network address resources are limited, th
In Windows 7 above system, when setting the local IP address often see colleague contains IPV4 agreement item and IPV6 Agreement item, Inquire IPV6 and IPv4 difference, the following small series for everybody introduced under IPV6 and I
Translation, RFC2765)
SIIT defines the translation method between IPv4 and IPv6 packet headers. This translation is stateless, So translation is required for each group. This mechanism can be combined with other mechanisms (such
tunnel and automatically configured tunnel. Tunnel Technology cleverly utilizes the existing IPv4 network. It provides a method to enable communication between IPv6 nodes during the transition period, but it cannot solve the problem of communication between IPv6 nodes and IPv4 nodes.

Implement transparent intercommunication between IPv4 and IPv6
According to Li Qing, Chief Scientist and senior technical expert of BlueCoat, In this security gateway solution, BlueCoatProxySG device-a secure acceleration proxy device-acts as an intelligent intermediary between access re
1. Background knowledge
With the continuous development of personal computers, mobile terminals and even the internet of things, there is a great demand for IP addresses. As the IPV4 protocol was designed without expecting that the network would be so developed in the future, the number of IP in the IPV4 network seemed to be stretched relative to today's demand. Add IPV
We are not unfamiliar with the technology of tunneling, and apply it to the interworking between IPv4 and IPv6. Tunneling technology has played an important role in this transitional technology, so let's take a look at some of the relevant terminology and standards for interoperability.
What are the common technical standards for IPV4 and
For IPv6 translation, the new saying is: "The Dual stack can be used where the dual stack can be used, and the tunnel is used where the tunnel has to be used ."
Users are concerned about how to migrate data from IPv4 to IPv6. In the current application, IPv6 mainly uses the
-acts as an intelligent intermediary between access requests and content, make the applications, services, and data retrieval of IPv4 and IPv6 in the environment transparent to users. To avoid network interruptions and simplify migration, Blue Coat ProxySG devices can stably execute enterprise IT policies across IPv4 and IPv6
There are many communication methods between IPv6 and IPv4, but they are all based on tunnel technology. In the previous article, we have already mentioned many tunneling technologies related to IPv6 and IPv4. We will not introduce them here, but mainly summarize the communication methods of the two. Now, please refer
First, IntroductionLet's assume that the hosts discussed in this chapter support dual stacks, that is, support for IPV4 addresses, and Ipv6 addresses.We are talking about the point: the client and server side use different types of addresses. Because the same type of address has nothing to say.Second, IPV4 client and IPV6
We all know the essential differences between IPv6 and IPv4 protocol networks. So what are the differences between the two in the two-way session communication process? The following describes the content in detail. The NAT-PT can only be used for applications that initiate a session by a terminal in the Ipv6 network, and the NAT-PT cannot be implemented if an ap
