You've lost me a bit. You usually use multiple, public IPs to support incoming connections, not outbound. Using public IPs sometimes makes it easier to support services, or multiple gaming systems (XBOX, PS3) where you would need port mapping of the same ports to different internal IPs (not possible w/ NAT), etc. For outbound connections, a single public IP over NAT is rarely a problem.
So again, I'm not sure I understand the need or purpose of these IPs. I’d just hate to see someone spend money needlessly.
I'll admit it - I made an entire macro program for a game, and want to farm money at an insane speed. Using multiple outgoing IP's, even if one gets found my entire operation wont get banned simultaneously.
Morally wrong... maybe. Legally, not even close.
PS: Yes i can sleep at night knowing im a gold farmer.
2nd PS : I wrote it because it was hard, it was challenging. I'm a 20 year old who does this for fun. I've already effectively won the game, this was my next level of " I WIN "
