Highly reliable internet connectivity is where enterprise networking and service provider networking come together—two disciplines that tend to apply the same technologies quite differently.
The six main areas that are relevant here are:
inet6 consult is owned and operated by Iljitsch van Beijnum in The Hague, the Netherlands.
Iljitsch got his start in the Dutch Internet Service Provider business in 1995. He soon realized that in order to maintain more than one connection to the internet, you need something called "BGP". In 1997, he co-founded Pine Internet (later Pine Digital Security). In 1999, he worked for UUNET Netherlands on designing and implementing a new Dutch high speed backbone based on the UUNET US design.
In 2000, Iljitsch started his own business under the name Muada, now called inet6 consult. Between 2000 and 2007, he mostly did work for web hosting companies. In 2002, he authored "BGP, Building Reliable Networks with the Border Gateway Protocol" for O'Reilly, and in 2005 "Running IPv6" for Apress. He also started attending IETF meetings in 2002.
In 2007, Iljitsch started writing for Ars Technica. Later that year he moved to Spain to become a research assistant at UC3M, where he did more IETF work, most notably on NAT64 and DNS64. Full list of publications. Iljitsch holds a bachelor's degree in Information and Communication Technology from the Haagse Hogeschool and a master's degree in telematics from UC3M.
After returning to the Netherlands, in 2016 Iljitsch joined Logius, an agency of the Dutch Ministry of the Interior and Kingdom Relations. As a network architect, he was responsible for the Dutch government-wide IPv6 numbering plan. In 2019 he left Logius to return to being independent.
