What is an IP address?
An Internet Protocol address (IP address) is a human readable number that is assigned to each network device/network interface on a computer network that uses the Internet Protocol for communication. One one hand the IP address serves as a network interface identification, on the other hand an IP address serves for location addressing. Most common version that is used nowadays for public IP adresses is the IPV4 standard. It defines an IP address as a 32-bit number. However the huge growth of the the internet with more and more connected devices in the last years lead to development of IPv6. With IPv4 every IP address has now 128 bit. Unfortunatly it is still difficult to switch from IPv4 to IPv6. Both IPv4 and IPv6 do have private versions, since not all IP addresses need to be accessed publicly. These IPv4 and IP46 private ones can be used in internal networks and do not need to be coordinated with public IP address registries.
