$ ifconfig

This will display the network interfaces on your machine along with their IP addresses. Look for the interface name associated with your network connection, such as "eth0" or "wlan0". The IP address will be listed next to the "inet" field.

If your Ubuntu machine is not obtaining an IP address via DHCP, you can try releasing and renewing the IP address manually using the following command:

$ sudo dhclient -r                                       # Release the current IP address
$ sudo dhclient                                           # Request a new IP address

This will attempt to release the current IP address and request a new one from the DHCP server.

Configuring DHCP Settings

If you need to manually configure your DHCP settings in Ubuntu, you can do so by editing the network configuration file. The file is located at "/etc/network/interfaces".

To manually assign a static IP address instead of using DHCP, you can modify the file as follows:

auto eth0
iface eth0 inet static
address 
netmask 
gateway 

Replace "" with your desired IP address, "" with the subnet mask, and "" with the default gateway. Save the file and restart the networking service for the changes to take effect.

Summary

DHCP is a network management protocol used to automatically assign IP addresses to devices on a network. Ubuntu is configured to obtain IP addresses via DHCP by default. You can check the assigned IP address using the "ifconfig" command and release/renew the IP address manually if necessary. If you need to configure DHCP settings manually, you can edit the "/etc/network/interfaces" file to assign a static IP address.
