Have you got banned some place and would like to change your IP address?
It's very simple, change your MAC address (only last 2 letters), restart your pc, modem (do a power cycle) and you've got yourself a new IP.
Step 1: (If you know how to find out your MAC Address, skip to step 2)
Start > Run > cmd
When command prompt appears, type in 'ipconfig /all'
Physical Address is your MAC Address.
Step 2:
System properties (right click on My Computer, properties) > Hardware > Device Manager > Find you network adapter and go to its properties. Go to Advanced and click on Network Address, check next to the empty box and write a new MAC Address. *Make sure you enter your new MAC address without hyphens or spaces.
