Here’s how to tell apart the following IP addresses: IPv4 and IPv6. When it comes to IPv4 and IPv6 addresses, these are mainly used to find your location and identify who you are. However, using it an IPv6 address has 128 bits makes the number of individual addresses that can be created exponentially larger.
