Uses 128-bit addresses to uniquely identify devices connected to the Internet. and 8203?

The technology that uses 128-bit addresses to uniquely identify devices connected to the internet is IPv6 (Internet Protocol version 6). IPv6 was developed to replace IPv4 due to the exhaustion of available IPv4 addresses. It allows for a vastly larger address space, accommodating the growing number of devices connected to the Internet. The mention of "8203" does not directly relate to standard Internet addressing protocols.
