Description
Technical field
The present invention relates to internet area more particularly to home router fields, in particular to a kind of realization to automatically update
The lower method and system for hanging IP address of equipment function.
Background technique
Under normal circumstances after gateway modifies own IP address, standby weight can be hung to allow down by lan mouthfuls of up down
New to obtain address by DHCP, although address can be reacquired by doing so, down may cause relevant after falling lan mouthfuls
Interface synchronization down falls, these interfaces is caused to disconnect in the data flow of forwarding always, influences user's use.In the router, under
Hang it is standby address is obtained by DHCP, the address and gateway address are in same network segment, after modify gateway address, under hang for and also
It is maintained at original address, at this moment just will appear the phenomenon that can not surfing the Internet.

Preferably, the response instruction in the step (3) is DHCP reply message.
The lower method and system for hanging IP address of equipment function are automatically updated using realization of the invention, are not influencing data
In the state of forwarding, lower extension IP address of equipment is automatically updated, interface is avoided and is disconnected during forwarding data flow, and then is influenced
User uses.The technical program is not necessarily to extra operation, more conveniently and quickly.
Detailed description of the invention
Fig. 1 is the flow chart that realization of the invention automatically updates the lower method for hanging IP address of equipment function.
Specific embodiment
It is further to carry out combined with specific embodiments below in order to more clearly describe technology contents of the invention
Description.
The realization of the invention automatically updates the lower method for hanging IP address of equipment function, including:
(1) gateway modifies own IP address, and sends all devices of reconfiguration instructions to lower extension；
(1.1) it is hung under for address is obtained by DHCP message；
(1.2) gateway modifies own IP address；
(1.3) gateway sends all devices of reconfiguration instructions to lower extension；
(2) it is hung under for judging whether to receive message, if it is, continuing step (3)；Otherwise, former IP address is kept,
Exit step；
(3) gateway hangs the more new command that preparation is sent under receiving, and sends response instruction and update lower extension IP address of equipment；
(3.1) preparation is hung under send more new command to gateway, and updates the IP address of itself；
(3.2) it is sent under response instruction updates with hanging device IP after hanging standby more new command under gateway reception is described
Location.
As the preferred embodiment of the present invention, the reconfiguration instructions in the step (1) are that DHCP reconfig disappears
Breath.
As the preferred embodiment of the present invention, the more new command in the step (3) is DHCP renew message.
As the preferred embodiment of the present invention, the response instruction in the step (3) is DHCP reply message.
Of the invention should be realized based on the above method automatically update lower system for hanging IP address of equipment function, including with
Lower step:
Router hangs standby more new IP address under notice when IP address for more new gateway；
Under hang standby, be connected with the router, the information for being sent according to router automatically updates IP address；
IP address automatically updates program, the IP address automatically update program at runtime automatically gateway with updating IP
Standby IP address is hung when location under synchronized update, specifically follows the steps below processing:
(1) gateway modifies own IP address, and sends all devices of reconfiguration instructions to lower extension；
(1.1) it is hung under for address is obtained by DHCP message；
(1.2) gateway modifies own IP address；
(1.3) gateway sends all devices of reconfiguration instructions to lower extension；
(2) it is hung under for judging whether to receive message, if it is, continuing step (3)；Otherwise, former IP address is kept,
Exit step；
(3) gateway hangs the more new command that preparation is sent under receiving, and sends response instruction and update lower extension IP address of equipment；
(3.1) preparation is hung under send more new command to gateway, and updates the IP address of itself；
(3.2) it is sent under response instruction updates with hanging device IP after hanging standby more new command under gateway reception is described
Location.
As the preferred embodiment of the present invention, the reconfiguration instructions in the step (1) are that DHCP reconfig disappears
Breath.
As the preferred embodiment of the present invention, the more new command in the step (3) is DHCP renew message.
As the preferred embodiment of the present invention, the response instruction in the step (3) is DHCP reply message.
In a specific embodiment of the invention, being related to hanging under after gateway address in the router changes standby can not surf the Internet
Problem.Way of the invention is to hang standby to carry out address update in the case where automatically generating a kind of message announcement after modifying gateway address.
If standby using being hung under DHCP reconfig message announcement, lower extension IP address of equipment can be automatically updated, is not needed
Extra operation more conveniently and quickly, while not influencing user's use.
As user since certain is needed, after having modified the IP address of gateway, do not need to update lower extension by plug cable
The IP address of equipment, but router sends to hang under DHCP reconfig message informing automatically and change for own IP address
Become, it is desirable that under hang the standby IP address to update oneself.
DHCP reconfig message is sent after gateway modification IP address of the invention, is hung under making for IP is automatically updated
The function of address, the method being directed to the following steps are included:
(1) it is hung under for address is obtained by DHCP message；
(2) gateway is since certain needs to modify own IP address；
(3) after gateway modification own IP address, DHCP reconfig message is sent to all equipment of lower extension；
(4) after being hung under for DHCP reconfig message is received, DHCP renew message is sent to gateway, updates oneself
IP address；
(5) it after gateway receives DHCP renew message, sends and hangs IP address of equipment under DHCP reply information updating；
(6) IP address of equipment is hung under updates completion, it is normal to surf the Internet.
The lower method and system for hanging IP address of equipment function are automatically updated using realization of the invention, are not influencing data
In the state of forwarding, lower extension IP address of equipment is automatically updated, interface is avoided and is disconnected during forwarding data flow, and then is influenced
User uses.The technical program is not necessarily to extra operation, more conveniently and quickly.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the invention.Therefore, the description and the appended drawings should be considered as illustrative
And not restrictive.
