There are two ways an ISP can allocate or assign an IP address to you for use on the internet: static or dynamic.

Static IP Address

A static IP address is assigned to your computer by your ISP and is permanent. Each time you connect to the internet, the same address is used. This address is never used by any other computer or device.

Dynamic IP Address

It would be simple if every computer that connects to the Internet could have its own static IP address, but when the Internet was first conceived, the architects did not foresee the need for an unlimited number of IP addresses. Consequently, there are not enough IP addresses to go around. To get around that problem, many Internet service providers economize on the IP addresses they possess by temporarily assigning an IP address to each computer from a pool of IP addresses. The temporary IP address is called a Dynamic IP address. As a result, the IP address may be different each time the computer connects to the Internet.

"Ping time"(Also refered to as 'Latency) refers to the amount of time it takes for a small "packet" of data to travel over the internet from one computer to another computer and back to the first computer. It is usually reported in milliseconds (ms).

Yes, RoadRunner blocks the following ports for security purposes:

•Port 137 UDP NetBIOS Name Service - Used for Windows File and Printer Sharing
•Port 138 UDP NetBIOS Datagram - Used for Windows File and Printer Sharing
•Port 137 TCP NetBIOS Session - Used for Windows File and Printer Sharing
•Port 445 SMB over TCP and UDP - As of Windows 2000, replaced the three ports listed above and still used for Windows File and Printer Sharing.

These ports are only blocked for traffic flowing into and out of your cable modem, they do not, in any way, affect local file sharing on your network, nor do they affect any P2P (Peer-to-Peer) program known.

**It should be noted, if you require access on any of these ports, RoadRunner Business Class in your area most likely does not block these ports and if they do, will likely unblock them upon request.
