An Internet Protocol address (IP address) is a unique number assigned to every device that connects to the internet. Your computer, mobile phone, tablet, and even your smart TV all have an IP address.
IP addresses are used to identify your network and location. There are two types of IPs: IPv4 and IPv6. The difference between the two is the number of possible addresses. IPv4 only allows 4 billion, whereas IPv6 will never run out.
