As the international administrator of the top-level domains ICANN makes the guidelines for allocation and registration of those. At this workshop they will inform about their work as regards DNSSEC signing and how the root zone is run. ICANN gather various actors to make overall rules for generic top-level domains (such as .com, .org or .shop). The workshop will go through some of ICANN's initiativs for these top-level domains.
ICANN consider this workshop to be useful both for those with former experience with ICANN and for new actors in the business.
