Lars-Johan holds a Master of Science degree in Engineering Physics from the Royal Institute of Technology (KTH) in Stockholm, Sweden. His career started at the Network Operations Centre at the KTH where he contributed to the operation of the DNS servers, especially i.root-servers.net. Lars-Johan’s keen interest in the DNS soon made him responsible for the service, and when Netnod AB was formed as a spin-off from the university to take over the operation of infrastructure services (including I-root), he became its first employee. Lars-Johan remains in charge of the service, which nowadays encompasses 75+ service points around the globe. His involvement with the community has carried him to leading positions in committees within the IETF and ICANN, and he is involved wherever root-server operations is discussed.
