In this course we'll use the '''ip''' command instead (you're welcome to use the old commands but you're expected to know the new ones too). The following table displays a comparison between ipconfig and ip commands, as well as other common commands to obtain your current settings network setting: <table border="1" cellspacing="0" cellpadding="2"><tr><td>Purpose</td><td>Older Method (command)</td><td>Newer Method (command)</td></tr><tr> <td>Obtain IP ADDRESS and Subnet Mask</td><td>ifconfig</td><td>ip address</td></tr> <tr> <td>Obtain Default Gateway</td><td>route -n</td><td>ip route</td></tr> <tr> <td>Obtain DNS Server</td><td>nslookup</td><td>more resolv.conf</td></tr> <tr> <td>Purpose</td><td>uname -n</td><td>Same</td></tr> </tble>
In OPS235 you've used the ifconfig and route commands. In this course we'll use the ip command instead (you're welcome to use the old commands but you're expected to know the new ones too).
