How do you think you must support ipv6 in the future?

Internet Protocol version 6 (IPv6), is a version of Internet Protocol (IP), defined in RFC 2460 and designed to replace Internet Protocol version 4 (IPv4) RFC 791, which by 2016 is being implemented in the vast majority of devices who access the Internet.

IPv6 supports about 670 billion billions of addresses per square millimeter of the Earth's surface.

IPv6 includes more efficient and robust mobility mechanisms which will benefit not only telephone users and mobile devices, but also (for example) having good internet connections during airplane flights.

Answer:

IPv6 has been designed to be extensible and offers optimized support for new options and aggregates, allowing improvements to be made in the future.
