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

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.

Depending on the deployment speed of the existing IPV4 address, the remaining address will be exhausted in 10-20 years. Therefore, the network gradually from IPV4 to IPv6 conversion is inevitable, the corresponding various network applications will

1. What isIPv6 IPV6 refers to the Internet Protocol (IP) version 6th. At present, we mainly use Internet Protocol Fourth edition, namely IPv4. With the global Internet highly developed today, IPV4 address resources have dried up and the internet is

In order to expand the network, we use the IPv6 protocol. As an improvement of the previous version protocol, the address type in the traditional sense is no longer applicable, now let's analyze the types of IPv6 addresses and basic knowledge about

In the network, we all know that there are currently two versions, one is IPv4 and the other is IPv6. Different from the IPv6 protocol addresses of traditional networks, IPv6 supports a wider IP address space. But why? Now let's talk about the IPv6

There are three types of IPv6 addresses: global unicast addresses (public addresses), local links (communications on the same link), and loopback addresses. No addresses are specified, A unique local address (private address) with an Ipv4 address

NAT principles of IPv6 and MAP66 1. Why is NAT not recommended in IPv6 standards? This is a problem. As I explained earlier, IPv4 NAT breaks the Internet's "interconnection" feature, making some IP addresses no longer accessible in two directions,
