What's the difference between Static IP and Dynamic IP?
Dynamic IPs are renewed every time you restart your system. Usually this number is different every time since its pulled out of a pool of available Dynamic IPs from the Spectrum Business system. Static IPs are assigned to our clients who purchase them. The client's Static IP is always the same, which is a necessity when you are running a web server, mail server or any piece of equipment that needs to have the same IP address every time you access it.
How do I know if I need a Static IP or a Dynamic IP?
If you only need Internet access and don't require outside users the ability to access your internal systems then Dynamic IP may fulfill your needs. However, if others do require outside access to your systems internally hosted (i.e. web, email, FTP or VPN services) then you will need a Static IP.
Enhanced Services Available with Static IP product
The Static IP product provides a mixed public and private IP addresses solution. In addition to providing IP routing capability for the allocated public IP addresses, the cable router provides DHCP server functionality to client PCs with IP addresses from their private range. Privately addressed PCs will be enabled to access the Internet via TCP Port Address Translation to a single public IP addresses configured on the cable router. In addition, this configuration allows client printers and other nonpublic servers with private IP addresses to remain on their network.
Configuration of IP Address on my Router
One address is for the Ethernet interface. However, since an IP subnet has an all zero address and a broadcast address as well, 3 IP addresses are "used" per subnet. The gateway or router address is often the second address in the subnet.
Attaching Devices to my Commercial Router
The commercial Static IP routers come with either a 1 or 4-port switch (or hub). Additional devices can be attached via an external hub/switch.
