Yes, any device that connects to the internet or a local network needs an IP address to function. Without one, a device cannot send or receive data, browse websites, send emails, or connect to any online service. This applies to computers, phones, tablets, smart TVs, printers, and any other internet-connected device. You do not need to manually set up or manage an IP address in most cases, since your router or internet provider assigns one automatically through a process called DHCP. IP addresses work in the background to make internet communication possible, so while you rarely think about them directly, every device you use online depends on having one.
