ID: G00203257

Analyst(s): Jeff Young


The Internet Protocol Next Generation (IPng), or Internet Protocol version 6 (IPv6), has been in development for more than 10 years without seeing widespread deployment. What has happened in those 10 years? What are the most likely ways for an enterprise or individual to become involved in IPv6? Burton Group Senior Analyst Jeff Young revisits the topic in a new IPv6 technology overview.
