RoadRunner and Multiple IPs

Has anyone worked with a RoadRunner account with Multiple IPs?
Would I be given a router that will separate each IP or would I have to purchase a router that would separate the IPs from the cable modem? If I would need to purchase a separate router, do you know of any inexpensive (albeit, still reliable) routers that will work with multiple IPs?

    I have Wide Open West, but it should work the same way. I have three static IPs.

    I have: Cable modem --> 5 port switch. This switch is my "internet only" switch. From the switch I have 1 port going out to my smoothwall router WAN side for my "home computer" IP. The router LAN side gets plugged into a 24 port switch for all my workbench and home computers.

    Another cable on the 5port "internet" switch gets plugged directly into my dev server, which also has a static IP. basically anything that gets plugged into the 5 port "internet" switch needs to have a static IP.

    Does that make sense?

    I think it makes sense, but let me say it the way I'm visualizing and you tell me if I have it correct.

    WOW gives you IPs 1.1.1.1, 1.1.1.2 and 1.1.1.3
    Cable modem doubles as a switch.
    Plug device 1 into the cable modem and assign that device IP 1.1.1.1
    Plug device 2 into the cable modem and assign that device IP 1.1.1.2
    Plug device 3 into the cable modem and assign that device IP 1.1.1.3
    Is that correct?

    Can I just buy an inexpensive router that will allow me to assign multiple IPs via which port they are plugged into, or would a router that can handle multiple IPs be several hundred dollars?

    Nope - cable modem does not double as a switch. Cable modem is nothing more than a transceiver.

    Plug Cable modem into small switch

    Plug device one into switch and assign it 1.1.1.1
    Plug device two into switch and assign it 1.1.1.2
    Plug device three into switch and assign it 1.1.1.3

    Problem is, you can't have NATted machines on that same switch, cause they will attempt to pull IPs direct from the cable company (and succeed).. So you if you have any NAT machines, they have to be behind one of those "devices" - either 1, 2, or 3. Meaning device 1, 2, or 3 has to be any router.

    I understand. Thank you very much, Brian. :D
