Try using the arrow keys and function keys to bring up previous commands. Type the command cls ?.

Implementing TCPIP in the Command Line | 101 showing “more” at the bottom of each screen of information. Press the space bar to show the next screen of information. Or, to show one line at a time, press the Enter key. The ipconfig and ping commands are probably the two most commonly used commands when analyzing and troubleshooting networking issues. Although ipconfig displays infor- mation, it can also be used to make basic configuration changes and reset certain facets of DHCP and DNS. Ping is used to test connectivity to other hosts; here, command-line results tell you whether a remote host is “alive” on the network. ANALYZE AND CONFIGURE WITH IPCONFIG AND PING In this exercise, you will learn more about ipconfig and ping, their switches, and how to use them effectively when troubleshooting.

1. Type the command ipconfig.

This should display results similar to Figure 5-3. The ipconfig command displays information pertaining to your network adapter, namely TCPIP configurations. Working with Ipconfig and Ping Ipconfig and ping can be used to analyze, test, troubleshoot, and configure IPv4 and IPv6 connections. Before moving to more advanced TCPIP commands, it is important to master these commands by learning what each of the commands and their options do, as well as why you would use those options in a real-world scenario. CERTIFICATION READY How do you analyze TCP IP with ipconfig and ping? 3.6 Disable any firewalls hardware or software that might interfere with the following exercises and tests. TAKE NOTE Figure 5-3 Ipconfig command Your IP address and other actual configurations might be different. Regardless, this is where you can find out the IP address, subnet mask, and default gateway of your network adapter. IPv4 and possibly IPv6 information will be listed depending on your configuration. Note that this is not all the information ipconfig can display. If you wanted to know the MAC address of the network adapter, for instance, you could use one of several options of ipconfig.
