Does CM1150V support multiple global IP addresses?

I'm a newbie here, so please be kind....

I just would like to know if CM1150V cable modem supports Comcast network with multiple global IP addresses.  I'd like to increase my download & upload speed and CM1150V appears to be what I need, but I currently am getting multiple global IP addresses from Comcast and having multiple global addresses is a lot more important than having better speed.

I'd appreciate your input.  Thanks in advance.
