Problems solved by technology

[0004] It can be seen that the IPv6 address contains 128 bits, and the global prefix generally does not exceed 64 bits. If the remaining bits are only used for address identification, it is obviously a waste
Especially at present, the address allocation

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0026] figure 1 A physical structure diagram of virtual host IPv6 address allocation in the embodiment of the present disclosure is schematically shown. Depend on figure 1 It can be seen that the structure includes a first router, a prefix issuing device, various network domains, a central server, and a virtual host. In the process of assigning an IPv6 address prefix, the prefix issuing device can issue the prefix to the second router of the Internet operator , the second router of the Internet operator then allocates and issues the third IPv6 address prefix level by level until it is allocated to the end device, namely the virtual host, and the prefix issuing device can also directly issue the IPv6 address prefix to the...

Abstract

The invention provides an IPv6 address generation method of a virtual host. The method comprises the following steps: S1, a first router sends a first IPv6 address prefix with a length of 32 bits to aforward affix sending device, and the prefix sending device downwards connects a second router with different network domain sizes and a virtual host; S2, the prefix issue device allocates an IPv6 address prefix with a length of N bit to the second router according to the first IPv6 address prefix and the network domain size, and the prefix issue device allocates a second IPv6 address prefix witha length of 64 bits to the virtual host according to the first IPv6 address prefix; 3, the virtual host obtains a symmetrical key from the central server, and encrypts the information of the virtualhost to generate 64 bits after IPv6 address according to the symmetrical key; S4, the 64-bit second IPv6 address prefix and the 64 bits after the IPv6 address are spliced to generate an IPv6 address.Another aspect of the disclosure also provides an electronic device, an IPv6 address generation system, and a computer readable medium.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method, device, system and medium for generating an IPv6 address of a virtual host. Background technique [0002] At present, with the widespread application of Internet technology, IPv4 (Internet Protocol Version 4) addresses are gradually exhausted, and the development of a new generation of IP address generation technology has become an urgent need for the development of the Internet. Therefore, IPv6 (Internet Protocol Version 6) address generation technology came into being , The most significant advantage of IPv6 is that the generated IP address can reach 128 bits, and the massive address space solves the problem of IPv4 address depletion day by day. [0003] IPv6 can use two address auto-configuration protocols, namely stateless address auto-configuration protocol (SLAAC) and IPv6 dynamic host configuration protocol (DHCPv6). When using SLAAC, there is no need for t...
