What is an Internet protocol (IP) address? With regard to an IP address explain what is meant by A, B and C class? What is the difference between a Static IP and a dynamic IP? Where are each of these used? Which of these would you term as better in terms of security?
The IP address or the Internet Protocol address is the numerical label or mark assigned or allocated to every device joining a computer network that applies or uses IP or Internet Protocol for its communication. The IP address provides 2 main functions: location addressing and network interface identification or network interface ID.
When you have a static IP address, this means you have a fix IP address. In other words, your IP address will not change. Your device will always use the same IP address every time it connects to a network. In a dynamic IP address, here your IP address constantly changes.
The majority of devices use dynamic IP addresses because it is the network that assigns it whenever the device connects. A dynamic IP address is a temporary IP address because it can change over time.
