Ip là gì?Before you can change your IP you need some information. This information includesyour IP range, subnet mask, default gateway, dhcp server, and dns servers.1. Getting your IP range - Getting information about your IP range is not difficult, Irecommend using Neo Trace on your own IP. But for my test just look at your IP address,say its 24.193.110.13 you can definitely use the IPs found between 24.193.110.1 < [newIP] < 24.193.110.255, dont use x.x.x.1 or x.x.x.255. To find your IP simply open ados/command prompt window and type ipconfig at the prompt, look for IP Address. . . .. . . . . . . . : x.x.x.x.2. Subnet Mask, Default Gateway, DHCP Server - These are very easy to find, just opena dos/command prompt window and type ipconfig /all without the . You should seesomething like this:Windows IP Configuration:Host Name . . . . . . . . . . . . . . : My Computer Name HerePrimary Dns Suffix . . . . . . . . . :Node Type . . . . . . . . . . . . . . .: UnknownIP Routing Enabled. . . . . . . . . : NoWINS Proxy Enabled. . . . . . . . : NoEthernet adapter Local Area Connection:Connection-specific DNS Suffix . . . . . . .: xxxx.xx.xDescription . . . . . . . . . . . . . . . . . . . . : NETGEAR FA310TX Fast Ethernet Adapter(NGRPCI)Physical Address. . . . . . . . . . . . . . . . . : XX-XX-XX-XX-XX-XXDhcp Enabled. . . . . . . . . . . . . . . . . . . : YesAutoconfiguration Enabled . . . . . . . . . : YesIP Address. . . . . . . . . . . . . . . . . . . . . : 24.xxx.xxx.xxSubnet Mask . . . . . . . . . . . . . . . . . . . .: 255.255.240.0Default Gateway . . . . . . . . . . . . . . . . . : 24.xxx.xxx.xDHCP Server . . . . . . . . . . . . . . . . . . . .: 24.xx.xxx.xxDNS Servers . . . . . . . . . . . . . . . . . . . . : 24.xx.xxx.xxx24.xx.xxx.xx24.xx.xxx.xxxLease Obtained. . . . . . . . . . . . . . . . . . .:Monday, January 20, 2003 4:44:08 PMLease Expires . . . . . . . . . . . . . . . . . . . .:Tuesday, January 21, 2003 3:43:16 AMThis is all the information you will need for now, I suggest you either keep yourdos/command prompt window open or copy & paste the information somewhere, to copyright click the window and select text and click once.III. Changing your IP AddressTo change your IP address first pick any IP you like out of your IP range and remember itor write it down. It is usualy a good idea to make sure the IP is dead (except for what weare going to do later on) so just ping it via ping x.x.x.x and if it times out then you canuse it. Now go to My Computer, then Control Panel. In Control Panel select NetworkConnections and pick your active connection, probably Local Area Connection or yourISP name. Open that connection by double clicking on the icon in Network Connections,then select Properties under the General Tab. In the new window that pops up selectInternet Protocol (TCP/IP) and click properties, its under the general tab. In this newwindow select the General tab and choose Use the following IP address and for the IPaddress enter the IP you would like to use (the one you picked from your subnet earlier)and for the Subnet Mask enter the subnet mask you got when your ran ipconfig /all, samegoes for the Default Gateway. Now select Use the following DNS server addresses andenter the information you got earlier. Now just click OK. Test that it worked, try torefresh a website and if it works you know everything is okay and you are connected. Tomake sure the change worked type ipconfig again and the IP address should havechanged to your new one.IV. DDoS & DoS ProtectionIf your firewall shows that you are being DDoSed, this is usually when you are constantlygetting attempted UDP connections several times a second from either the same IPaddress or multiple IP addresses (DDoS), you can protect your self by changing your IPaddress via the method I described above.V. Web servers & Other ServicesIf you know someone on your IP range is running a web server and he or she has pissedyou off or you just like messing around you can steal their IP address so any DNSgoing to that IP will show your site instead because you would be running a web serveryourself.To steal an IP is to basically use the changing IP address method above and picking anIP that someone that is running a web server has in use. Often you will be able to keepthat IP at least for some time, other times you wont be able to use it so just keep tryinguntil it works. You your self will need to have a web server on the same port with yourmessage. You can do this with other services too. You can also DoS or DDoS the IPaddress you are trying to steal to kick him off the net, but I dont recommend as its prettyillegal, an your ISP will get pissed ;)
