怎样才能让别人查不到自己的ip地址How to let others can notfind their IP address

ARP principle: a machine A to send the message to the host B,will query the local ARP cache table, to find the B address ofthe IP corresponding to the MAC address, it will be datatransmission. If not found, broadcast A, a ARP request message(carrying the host A' s IP address Ia - physical address Pa) ,requesting the IP address of Ib host B, and answering thephysical address Pb. All hosts on the Internet, including theB, receive the ARP request, but only the host B recognizes itsown IP address and sends back a ARP response message to the Ahost. This includes the B address of the MAC, and the local ARPcache is updated after the A receives the B response. The datais then sent using this MAC address (with the MAC addressappended by the network card) . Therefore, the ARP table of thelocal cache is the basis for the local network flow, and thecache is dynamic.

The ARP protocol does not receive the ARP response only whenthe ARP request is sent. When the computer receives the ARPresponse packet, it updates the local ARP cache and stores theIP and MAC addresses in the ARP cache. Therefore, when a machinein the LAN B to send A ARP response a forgery, and if thisresponse is B to C posing as the IP address forgery, C, IP, andMAC address is fake, then when A receives the ARP response Bforged, will update the local the ARP cache, so in A it seemsC IP address has not changed, but it is not the original oneMAC address. Because the LAN network flow is not carried outaccording to the IP address, but is transmitted according tothe MAC address. So the forged MAC address was changed to a

nonexistent MAC address on A, which would cause the network tofail and cause A to fail to pass Ping through C! This is a simpleARP spoofing.

2. , the network law enforcement officer is using thisprinciple!

In the network to a law enforcement official, to restrict themachine online, just click the"card"menu"permissions, selectthe card number or click on the list of users in the card row,select" permission"from the menu in the dialog box to restrictthe user' s permissions. For an unregistered network card, youcan limit its on-line: as long as the set of all known users(Registration) , the network card default permissions toprohibit on-line, you can stop all unknown network card on-line.With these two functions, users can be restricted to theinternet. The principle is to pass the ARP spoofing to theattack computer, a false gateway IP address corresponding toMAC, so that it can not find the gateway' s real MAC address,so that it can prohibit its access to the internet.

3. , modify the MAC address, break the blockade of the networklaw enforcement off icer

According to the above analysis, it is not difficult to drawa conclusion that as long as the MAC address is modified, wecan cheat the scanning of the Internet law enforcement officersoas toachieve the goal of breaking through the blockade. Hereis how to modify the MAC address of the network card:In the run of the start menu, enter regedit, open the registry

editor, and expand the registry to: HKEY_LOCAL_

MACHINE/System/CurrentControl

Set/Control/Class/{4D36E972-E325-11CE-BFC1-08002BE10318} key, 000000010002 sub branch in DriverDesc in the searchkey (if you have more than one card, there are 00010002. . . . . .here is keeping on your card information, the DriverDesccontent is the card information description, such as my cardis Intel 210

41, based, Ethernet, Controller) here, suppose your networkcard is in the 0000 child key.

Add a string under the 0000 child key, named NetworkAddress.The key value is the modified MAC address, which requires 12consecutive 16 hexadecimal numbers. Then, in the NDI/paramsunder the "0000" sub key, a new subkey called NetworkAddressis added. Under the subkey, a string called default is added,and the key value is the modified MAC address.

Under the child key of the NetworkAddress, continue toestablish a string called ParamDesc, which acts as thespecified Network

Description of Address,

Its value is "MAC Address"". Then open the network neighbor"attribute", double-click the network cardwill finda"senior"setting, the existence of MAC Address under the new

"NetworkAddress" option, it is for you to join in the registry,then as long as the MAC address can be modified.

Close the registry, restart, and your network card address hasbeen changed. Open the property of the network neighbor anddouble-click the corresponding network card entry to find anadvanced setting item of MAC Address for modifying the MACaddress directly.

The MAC address is also called a physical address, a hardwareaddress, or a link address. It is written inside the hardwarewhen it is produced by the network device manufacturer. Theaddress and the network that has nothing to do with this addressboth hardware (such as cards, hubs, routers) access to thenetwork where it will have the same MAC address, MAC addresswill not be changed, can not be set by the user. The MAC addressis usually expressed as a decimal number between 16 and 12, thenumber of 16 m each of the 2 separated by a colon, such as:

08:00:20:0A:8C:6D is an MAC address, the first 6 hexadecimalnumber 16, 08:00:20 represents the network hardwaremanufacturer' s serial number, it is allocated by IEEE, and then3 hexadecimal number 16 0A:8C:6D represents a network productthe manufacturer made (such as card serial number) . Eachnetwork manufacturer must ensure that each Ethernet device itmanufactures has the same first three bytes and different threebytes later. This ensures that eachEthernet device in the worldhas a unique MAC address.

In addition, the principle of network law enforcement officeris to send a computer to the MAC address of the false gatewayIP address through ARP spoofing, so that it can not find the

real MAC address of the gateway. Therefore, as long as we modifythe mapping from IP to MAC, the ARP spoofing of the networkadministrator fails and breaks the restriction of breakingthrough it. You can Ping the gateway in advance and then usethe ARP-a command to get the MAC address of the gateway. Finally,you can map the IP address of the gateway and its MAC addresswith the ARP -s IP card MAC address command.

4. find the one that makes you unable to access the InternetAfter removing the network administrator' s blockade, we can useArpkiller' s "Sniffer killer" to scan the entire LAN IP section,and then f ind the "promiscuous" mode of the computer, you canfind each other. The specific method is: run Arpkiller (Figure

2) , and then click the "Sniffer monitoring tool", in the"Sniffer killer" window, enter the start and end of the testIP (Figure 3) , click "start testing" on it.

When the test is complete, if the corresponding IP is a greenicon, the IP is in normal mode, and if it is a red hat, the cardis in promiscuous mode. It' s our goal, that this guy is messingwith cyber law enforcement officials.

While scanning, I'm in promiscuous mode, and I can' t countmyself in it!

It' s up to you to deal with each other when you find him. Forexample, you can use the Internet law enforcement officer toblock the other party
