IPv6 was standardized in RFC 1883 in 1995, 30 years ago. It was envisioned as the next Internet Protocol, eventually replacing IPv4. In late 2024, worldwide adoption was around 40% and a linear projection, based on the rate of adoption during the last 10 years, ended up predicting that migration would hit 100% around 2045. It can be argued that this is an optimistic take.

Where does this leave an SRE team in 2025 and thereafter? We will be broaching on a number of aspects to try and answer this question.

A Linux enthusiast, turned FreeBSD sysadmin, turned Linux sysadmin, turned systems engineer (somewhere along that path there’s a Devops hat as well), turned SRE, Alexandros has been in the space since 1999, starting as a hobbyist, then a professional. Currently working with the Wikimedia Foundation in a Principal SRE role, he has pushed forward for more virtualization, embracing the containerization and orchestration paradigm while putting out his share of fires.
