This tutorial shows students and new users how to find their Ubuntu 17.10 computer IP addresses. An IP address is like a phone number for your computer. It’s unique and assigned only to your computer.
IP addresses can be static – the one you type in yourself, or dynamic – addresses received from a computer automatically. Whether your desktop received its IP automatically or was entered manually, it will be unique.
Knowing your IP address can help you troubleshoot problems and your connections. Also knowing the different types of IP addresses may come in handy if something isn’t right. This brief tutorial is going to show you how to tell what to look for.
If your computer is having a connectivity issue, the first thing is to identify how it’s connected and what IPs are being used.
To find out, click the system menu at the top right corner of your screen and select System Settings as shown in the image below:
Then select Network from the list of items on the left to show the network pane.
On the network panel, you should see the desktop is connecting via a Wired connection and it is ON.
If your desktop was connected via a Wi-Fi connection, it would show Wi-FI and turned ON. To view the IP address assigned to the desktop, click the gear button to the right of the connection and will show you IP address information.
From the screen above, you can tell the IPv4 / IPv6 addresses, as well as the network identification number (Hardware Address). It also shows you the Default Route address and the DNS server address.
This network device is setup to connect automatically when your computer starts. You can click on the different tabs to setup manual or static addresses for the IPv4 or IPv6 networks.
These IP addresses are assigned to your computer automatically via a DHCP server. The server assigns the address, DNS and the Router (gateway) addresses. To set these addresses yourself, you can choose the Manual options.
Choosing Manual option assumes you know the correct information for your device. If the information you enter is wrong, your desktop network access will be limited or no access at all.
