Understanding IP Addresses:
Before delving into the process of blocking an IP address, let’s first understand what an IP address is. IP stands for Internet Protocol, which is a unique numerical label assigned to each device connected to a computer network. An IP address helps in identifying and locating devices on a network. It serves as a virtual “address” that enables data to be transmitted between devices over the internet.
An IP address consists of four sets of numbers separated by periods (e.g., 192.168.0.1). The IP address can be either dynamic or static. A dynamic IP address is assigned by the internet service provider (ISP) and may change over time, while a static IP address remains fixed.
Blocking an IP Address:
Blocking an IP address can be an effective way to prevent unwanted access to your network or to restrict certain individuals or entities from accessing your online resources.
Whether you want to block an IP address due to security concerns or to maintain a certain level of privacy, the process can be relatively straightforward.
