Mirjam Kühne gave a presentation at re:publica in Berlin on May 2nd about maintaining internet infrastructure. She discussed how the internet is made up of different layers including protocols, IP addresses, and autonomous systems. She explained that organizations like RIPE and the IETF help coordinate these systems through open, collaborative processes. Maintaining unique IP addresses and distributing them appropriately is important for the functioning of the internet. Participation in these coordination efforts helps protect the collaborative model that has supported the growth of the internet.
