How can I check the IP address settings on my Chromebook to see if they are configured correctly?

Go to Settings > Advanced > Network > Ethernet or Wi-Fi. Look for the 'IPv4' or 'IPv6' settings. They should usually be set to 'Automatic (DHCP)'. If they are set to 'Static', it means you've manually configured the IP address, which might be incorrect. Ensure the IP address, gateway, and DNS server addresses are valid and correct for your network.
