About IPv4 and IPv6
IPv4 uses a 32-bit address space, providing about 4.3 billion unique addresses. IPv6 was developed to replace IPv4, using a 128-bit address space, which provides a virtually unlimited number of addresses.
As the internet transitions to IPv6, various transition mechanisms are used, such as IPv4-mapped addresses, which allow IPv6-only applications to communicate with IPv4 nodes.
