Here I share the way I get new IP address using Cable Internet and running multiple account on one PC and one user account.
If you have better way please share
Again, This thread just apply to people who using Cable Internet only. Suddenlink is what I have.
I have a cheapest cable plan, less than $30/month and bought my own modem on eBay for less than $30. I prefer the Netgear CG814xxxx model because it have 4 RJ45 port so you can have 4 different PC connect at the same time and get 4 different IP address. Just search "Haxoware Netgear" on eBay you will find it.
I'm not using a router or wireless router. Just connect direct from PC to the modem. This way, when I need a new IP I just change the MAC on that PC.
1 Connection = 4 Output = 4 IP at the same time is good enough for me. I always can get more IP by running multiple VMware if I needed to.
I'm running multiple account with 1 user account but using FireFox Portable. Make 1 folder for each account and rename to folder name. Created shortcut for all of them on the Desktop (Account 1, Account 2.........)
I use TMAC Changer V5 to change MAC address
First time run the software
Click on the "Change MAC" button
Click on "Random MAC Address" button
Click "Change Now" button
Click "Create/Edit" button
Check "MAC Address", "Enable DHCP" check box. Select "Use" option and enter the name you want in the "Preset Name" field and "Save" it
Add as many account/MAC as you want. Next time if you want to change your MAC to get new IP. Just select the account you want from the drop down list
Hit me up if you have any question about this method.
