[Discuss] System receiving incorrect IP address

[Jerry Feldman]

Go into network settings, IPV4, make sure the setting is DHCP (automatic).
as well as automatic for DNS and routes. Do the same for IPV6. I am
assuming you only have 1 network interface. And, as you mentioned, your MAC
address cannot be spoofed.
