Changing ip address and how many ways can you change it?

The internet uses the IP protocol so if you are getting banned it's hardly going to be via your MAC address. Since they won't even know it. On the topic of changing your IP. Restarting your modem may or may not work depending on: your internet provider, the type of modem (type of connection, dial-up will most likely allways change it) And if you have a static or dynamic IP assigned. Of course it also depends on how they block you. Though it would be wierd for someone to block a range of ip's just to keep you out.

Your Public IP address is assigned to you by your Internet Service Provider. The first device in your house, the MODEM/Router is the device that has this IP address. Your Router then assigns a Different IP address to your computers, usually in the range of 192.168.xxx.xxx. You have no control over your Public IP. In some cases, if you turn off you modem for 24 hours, you may get a different one. It depends on how the DHCP server is set up at your ISP. If the DHCP server saves the MAC address of your Router in it's data base then it will keep assigning the same IP. The only sure fire way to change IP is to change your modem so the MAC address will be different or change ISP's.

Your IP address is assigned by your ISP. If you get blocked, there are only a few things you can do to change it. One involves turning your Modem off for a minimum of 1 hour. Then you "might" get assigned a new address. There is a protocol called ARP that keeps your Address in its registry till it hasn't heard from you for a default of 3600 seconds (1 hour). So you need to disconnect for more than that time. You can also use a proxy server. This adds LAG to games.
