Method and device for determining addresses in IPv6 (internet protocol version 6) based LAN (local area network)

Abstract

The invention discloses a method for determining addresses in the IPv6 (internet protocol version 6) based LAN (local area network), which is characterized in that the same parts of terminal address fields in the LAN are identified by set identifiers and comprises the following steps: replacing the same parts of the destination terminal address fields by the identifiers to serve as input destination addresses when initiating a service request; and determining an interface for forwarding the service request by a source terminal in an interface supported by the source terminal and converting the destination addresses into the addresses in the complete IPv6 form according to the destination addresses and the address of a currently selected interface by the source terminal. The invention also discloses a device for determining addresses in IPv6 based LAN. Identification addresses carrying identifiers are input to realize the communication of terminals in the LAN, and the source terminal is automatically converted according to the input address of a user so that the user can more conveniently access and maintain the terminals in the LAN. The technical scheme adopted by the invention is simple and practical.

Description

technical field [0001] The present invention relates to an address marking technology in a local area network based on IPv6 (Internet Protocol Version 6), in particular to a method and device for determining an address in a local area network based on IPv6. Background technique [0002] The Internet widely used in the world is based on the IPv4 (Internet Protocol Version 6) protocol. The IP address is represented by 32 bits. There are about 4 billion IP addresses in theory. In fact, only half of the addresses are available due to various restrictions. Moreover, considering that the demand for IP addresses will increase significantly due to the development of 3G terminals, IP phones, and home networks in the next few years, professional organizations predict that the global IPv4 addresses will be allocated in the first half of 2011. [0003] On November 7, 1994, the Internet Engineering Steering Group (IESG, Internet Engineering Steering Group) officially approved IPv6 as a s...

AI Technical Summary

Problems solved by technology

[0008] Although the length of the 128-bit address of IPv6 solves the problem of shortage of IP addresses well, it also brings a new problem in actual use: the IPv6 address cannot be accurately remembered because it is too long

However, for terminals in the LAN, there is usually no domain name, and they can only be accessed directly through IPv6 addresses, which brings great difficulties to the communication of terminals in the LAN

Moreover, a terminal that supports IPv6 often has multiple IPv6 addresses, especially the hand-held terminal is limited by the address input and display methods, and the problem is more prominent.
