TCP/IP Internet Basics

Network Equipment

Now that you have an idea of high-speed Internet access, you have to determine what type of

equipment you have on the site, so you will better understand how to connect your NVS to your

current network.

Router:

A router basically divides networks. Typically a router divides the network from the ISP’s

(Internet Service Provider) network and your local network. You must have a router to separate

these networks. You must have a router to share an Internet connection. If you have a single PC on

site that accesses the Internet and you want to enable another device to transmit over the Internet

(ex. NVS) you must have a router to share the Internet connection. If you already have multiple

PC’s or devices accessing the Internet, then odds are you already have a router installed. A router

essentially needs just two ports. One port links the remote network to the router and another port

from the router to your local network. For most home users, small office/home office routers have

a built-in switch to provide for multiple devices to connect to the router and share that main link to

the remote network. Let us assume that the remote network we are referring to is the ISP’s

network. On your router you should be able to identify several ports. There always should be one

port labeled ‘WAN’ or ‘Internet’. That WAN or Internet port is used to connect your ISP’s network

to your router. The other ports are the ‘switched’ ports, which allow you to connect multiple

Ethernet devices to the router to share the Internet connection. The image below shows a typical

home office router.

You notice that there is the one WAN port with 8 other Ethernet ports available for use. All routers

have at least 2 IP addresses, always. One IP address is to connect to your ISP and is assigned to

your WAN or Internet port and the other IP address is logically connected to all of the other

‘switched’ ports. For instance the WAN (public) IP from your provider could be 54.63.2.123 and

the other IP for your LAN (private) may look like 192.168.x.x.
