Configuring a TCP/IP Network— the Software Side Part 1

TCP/IP is software, and just like any software, it has to be installed. This topic describes the steps needed to get TCP/IP up and running. If you’re lucky, you might have no steps. Yet. After TCP/IP is installed — that’s the time you have to get to work and configure your system. Read on to […]

Configuring a TCP/IP Network— the Software Side Part 2

Configuring TCP/IP on a Mac OS X client Follow these steps to set up and configure TCP/IP on your Mac OS X client: 1. Choose System Preferences from the Apple Menu at the upper-left of the screen. 2. Click the Network icon Location pop-up menu and choose Automatic. 3. Access the Configure pop-up menu and […]

Configuring a TCP/IP Network— the Software Side Part 3

Setting TCP/IP Server Properties Setting up a server starts out with the same steps as setting up a client, but you’ll need to go beyond the default client setup steps described in the preceding section. Server software has lots more work to do than client software. A server reacts to requests from multiple clients. For […]

Networking SOHO with Wireless (TCP/IP) Part 1

Wireless networking is networking without using wires, satellite, regular cable, or fiber optic cable. Okay. Of course you know that, but we felt we had to say it so everyone who’s reading this topic uses the same definition as a starting point. So, the transmission medium is air in this topic. According to our definition, […]

Networking SOHO with Wireless (TCP/IP) Part 2

Step 3: Set up your Wireless router This step may seem complicated. That’s because it is. It’s also required. The good news is that you should only have to do it once, or (at most) once in a blue moon. Start with the wired side Gather this information from the router’s documentation and your ISP: […]

Advancing into Routing Protocols (TCP/IP) Part 1

The small multifunction routers shown in that topic’s SOHO figures connect a home or small office’s subnets to each other — and to the Internet. These small routers can forward packets at a rate ranging from 10 to 20 megabits (millions of bits) per second. That seems plenty fast, but get this: Routers for large […]

Advancing into Routing Protocols (TCP/IP) Part 2

Reaching the destination The message travels from the Internet’s router across the transmission medium and arrives at Google’s router, as shown in Figure 8-7. Figure 8-7: The information you asked for is almost at Google’s computer. These next steps take place there: 23. (Physical Layer – inbound) Google’s router receives the message. "Oh, look! A […]

Advancing into Routing Protocols (TCP/IP) Part 3

Understanding How BGP Routers Work When a BGP router first comes up on the Internet — whether as a new router or one that was off but has been turned back on — it connects with other BGP routers. It immediately copies the routing tables of each neighbor router. Then, after initially getting the routing […]

IPv6: IP on Steroids (TCP/IP) Part 1

At first glance, IPv6 protocols and addresses seem more complicated than in IPv4. Take a deep breath, count to ten, and rest assured that IPv6 can make your life a lot easier. Several IPv4 limitations led to the development of IPv6. Say Hello to IPv6 IPv6 is the Internet protocol designed to replace IPv4. The […]

IPv6: IP on Steroids (TCP/IP) Part 2

IPv6 Installation On new computers, IPv6 usually is installed by default. For example, because Windows Vista, Windows 7, and Windows Server 2008 have a dual IP architecture, they support both IPv4 and IPv6. Computers running these operating systems come from the factory with IPv6 already installed and enabled. You cannot uninstall IPv6, but you can […]
