Why Is IPv6 So Important for the Development of the Metaverse?

By Gabriel E. Levy B. and Alejandro Acosta

Over almost half a century, the TCP/IP protocols have helped connect billions of people.

Since the creation of the Internet, they have been the universal standards used to transmit information, making it possible for the Internet to function[3].

The acronym ‘IP’ can refer to two different but interrelated concepts. The first is a protocol (the Internet Protocol) whose main function is to be used in bidirectional (source and destination) data transmission based on the Open System Interconnection (OSI) standard[4]. The second possible reference when talking about IP involves the assignment of physical addresses in the form of numbers known as ‘IP Addresses’. An IP address is a logical and hierarchical identifier assigned to a network device that uses the Internet Protocol (IP). It corresponds to the network layer, or layer 3 of the OSI model.

IPv4 refers to the fourth version of the Internet Protocol, a standard for the interconnection of Internet-based networks which was implemented in 1983 for the operation of ARPANET and its subsequent migration to the Internet.[5].

IPv4 uses 32-bit addresses, the equivalent of 4.3 billion unique numbering blocks, a figure that back in the 80s appeared to be inexhaustible. However, thanks to the enormous and unforeseen growth of the Internet, by 2011 the unexpected had happened: IPv4 addresses had been exhausted[6].

IPv6 as a solution to the bottleneck

To address the lack of available address resources, the engineering groups responsible for the Internet have resorted to multiple solutions, ranging from the creation of private subnets so that multiple users can connect using a single address, to the creation of a new protocol called IPv6 which promises to be the definitive solution to the problem and which was officially launched on 6 June 2012[7]:

“Anticipating IPv4 address exhaustion and seeking to provide a long-term solution to the problem, the organization that promotes and develops Internet standards (the Internet Engineering Task Force or IETF) designed a new version of the Internet Protocol, specifically version 6 (IPv6), with provides almost limitless availability based on a the use of 128-bit addresses, the equivalent to approximately 340 undecillion addresses”**[[8]**.

It should be noted, however, that the creation of the IPv6 protocol did not anticipate a migration or shift from one protocol to another. Instead, a mechanism was designed to allow both protocols to coexist for a time.

To ensure that the transition would be transparent to users and to allow a reasonable amount of time for vendors to incorporate the new technology and for Internet providers to implement the new version of the protocol in their own networks, along with the IPV6 protocol itself, the organization responsible for Internet protocol standardization — the IETF — designed a series of transition and coexistence mechanisms.
