Step S110, obtains unappropriated IP address, by unappropriated IP address designation for nothing takies conflict situation IP address;
The present embodiment obtains unappropriated IP address from data center, by unappropriated IP address designation for nothing takies conflict situation IP address.
Step S120, to detecting without taking conflict situation IP address, judges that nothing takies conflict situation IP address and whether is converted to and takies conflict situation;
Preferably, detection mode is ICMP detection and address resolution protocol detection, what know current unallocated IP address by detection takies situation, judge to be designated and whether be not converted to take conflict situation without taking conflict situation IP address, in addition, the active situation of current unallocated IP address also can be known by obtaining address analysis protocol table from routing device.
Step S130, when nothing takies conflict situation IP address transition for taking conflict situation, will without taking conflict situation IP address designation for taking conflict situation IP address;
Nothing is being taken in the process of conflict situation IP address detection, active state is in without taking conflict situation IP address if find, then illustrating that this nothing takies the existence of conflict situation IP address and takies conflict, this nothing being taken conflict situation IP address designation for taking conflict situation IP address.
Step S140, when being still in without when taking conflict situation without taking conflict situation IP address, carries out the detection of variable length detection time interval to without taking conflict situation IP address.
To without taking in the process of conflict situation IP address detection, be in inactive state if find without taking conflict situation IP address, then illustrate that this nothing takies conflict situation IP address and do not exist and take conflict.Wherein, variable length detection time interval can increase successively for the time interval, first detect without taking conflict situation IP address with the shorter time interval, when being in without when taking conflict situation without taking conflict situation IP address duration, increase detection time interval gradually to detect, shorten the detection time of whole IP address range, reduce the network traffics that detected event produces.
The IP address detection method that the present embodiment provides, according to the historical results of IP address detected event, with variable length detection time interval, unappropriated IP address is detected, when unappropriated IP address is in without when taking conflict situation, first detect with the shorter time interval, if this unappropriated IP address duration being in without taking conflict situation, increasing detection time interval gradually and detecting, shortening the detection time of whole IP address range, reducing the network traffics that detected event produces.
Embodiment two:
Fig. 2 is the schematic flow sheet of the IP address conflict detection method that the embodiment of the present invention two provides.As shown in Figure 2, the IP address conflict detection method that the present embodiment provides specifically comprises the steps:
Step S210, obtains unappropriated IP address, by unappropriated IP address designation for nothing takies conflict situation IP address;
Step S220, to detecting without taking conflict situation IP address, judges that nothing takies conflict situation IP address and whether is converted to and takies conflict situation;
Preferably, detection mode is ICMP detection and address resolution protocol detection, what know current unallocated IP address by detection takies situation, judge to be designated and whether be not converted to take conflict situation without taking conflict situation IP address, when nothing takies conflict situation IP address transition for taking conflict situation, performing step S230, when being still in without when taking conflict situation without taking conflict situation IP address, performing step S240.
Step S230, will without taking conflict situation IP address designation for taking conflict situation IP address;
When step S220 judges, without when taking conflict situation IP address transition for taking conflict situation, without taking conflict situation IP address designation for taking conflict situation IP address, to provide discovery and taking collision alert information.
Step S231, detects taking conflict situation IP address, judges whether take conflict situation IP address is still in and takies conflict situation;
To taking in the detection process of conflict situation IP address, take conflict situation IP address if find and be still in active state, then illustrate that this takies conflict situation IP address and still exists and take conflict, step S232 will be performed, take conflict situation IP address if find and be in inactive state, then illustrate that this takies conflict situation IP address transition and takies conflict situation IP address for nothing, will step S233 be performed.
Step S232, carrying out maximum probe time detection for several times to taking conflict situation IP address, taking conflict situation IP address designation for taking conflict persistent state IP address;
When step S231 judged result for take conflict situation IP address be still in take conflict situation time, maximum probe time detection is for several times carried out to taking conflict situation IP address, by take conflict situation IP address designation be take conflict persistent state IP address while, provide discovery take conflict continue warning information.Wherein, maximum probe number of times preset before carrying out detected event to unallocated IP address.
Step S233, carries out basic detection time interval detection at least one times to taking conflict situation IP address;
When step S231 judged result takies conflict situation for taking conflict situation IP address transition for nothing, carry out basic detection time interval detection at least one times to taking conflict situation IP address.Wherein, basic detection time interval preset before carrying out detected event to unallocated IP address, and preferably, basic detection time interval span is 1 ~ 8 hour.It should be noted that, being set as at basic detection time interval 1 ~ 8 hour as a rule can detection flow preferably in balancing network and detection order of accuarcy, those having ordinary skill in the art will appreciate that, can set basic detection time interval according to the requirement of the concrete service condition of IP address and detection flow and accuracy, it is shorter that detection time interval, basis sets, corresponding detection flow increases, and accuracy increases; What also can set is longer, and corresponding detection flow reduces, and accuracy declines.

If S=0, then perform according to the following rules:
If a. 1. detection does not find unallocated IP address activity, then P=P+1 is set, ensures that P is no more than Pmax simultaneously.And F=P is set, indicate lower P detection time cycle, this unallocated IP address is not detected.
If b. 2. detection finds unallocated IP address activity, then T=Tmax is set, S=1, P=0, F=0, mark need continue to detect Tmax cycle, collision counter can be added 1 simultaneously, by unallocated IP address designation for finding conflict situation IP address, provide and finding conflict information.
If S=1, then perform according to the following rules:
If a. 3. detection does not find unallocated IP address activity, then arranging T=T-1, if now T=0, then arrange S=0, P=0, by unallocated IP address designation for without taking conflict situation IP address, disappearing to entry/exit conflicts simultaneously, recovery can distribution state information; Otherwise keep other parameter constant, be conflict temporary extinction state I P address by unallocated IP address designation, give entry/exit conflicts temporary extinction information simultaneously.
If b. 4. detection finds unallocated IP address activity, then arrange T=Tmax, mark need continue to detect Tmax cycle, collision counter can be added 1 simultaneously, is conflict persistent state IP address, provides unallocated IP address designation and find that conflict continues information.
If F is greater than 0, then F=F-1 is set, returns after postponing basic detection time C and continue to perform the F mark detecting each unallocated IP address, and operation afterwards.
In addition, the various parameter identification sum counter numerical value that in the present embodiment, each unallocated IP address is current with this unallocated IP address are kept in data logger, can by the detection mode of the entry amendment IP address in direct amendment record table.As the detection of certain unallocated IP address mark F is revised as 0, can force to detect this IP address at next detect cycle.
