IPv6 is a standard for assigning Internet Protocol (IP) addresses.
Every device that is connected to the internet needs to be assigned an IP address to connect. IPv6 is the new standard, introduced to replace IPv4 since 2012.
There is a relatively limited stock of IPv4 addresses left to be assigned. While IPv4 offers 4.3 billion addresses, IPv6 offers 340,282,366,920,938,000,000,000,000,000 billion addresses.
Many major broadband providers still assign Internet Protocol (IP) addresses using the IPv4 standard. When the stock is depleted, internet service providers will have to trade or lease addresses to allow new customers to connect to the internet.
