You log into your router administration panel using an IP address of 192.168.0.1. Which version of IP is this?

The IP address 192.168.0.1 is classified as an IPv4 address. This format consists of four octets, with each octet represented as a decimal number ranging from 0 to 255. In contrast, IPv6, which is a newer version of the Internet Protocol designed to address the limitations of IPv4, uses a hexadecimal format and is significantly longer, containing eight groups of four hexadecimal digits separated by colons. IPv1 and IPv2 are outdated or non-standard versions of IP that are not commonly recognized in current networking practices.
