In which case I claim that my PC at home is a highly critical infrastructure as well.

When I posted the following suggestion, it included a definition for critical infrastructure and your PC at home doesn't meet it. Suggestion... RIPE will allocate /24 blocks from the IPv4 address range that was once called "Class C" address space for use by services that are part of the Internet's critical infrastructure. These blocks are for services that will exist for the forseeable future, are used freely by many organizations, and are likely to outlive the lifetime of the organization currently operating the service. Your PC at home is not offering a service that will exist for the foreseeable future. I can forsee a future for the Internet into the 22nd century when you and your home PC will be dead. Your home PC is probably not offering a service that is used freely by many organizations. I think this part of the definition needs some work because some people would argue that Google's service meets this criteria but I would argue that part of Google's service are the ads which are not offered freely, i.e. they cost money. Your home PC is not offering any service that would continue to be offered even if you and your home and your company cease to exist. But if DENIC ceases to exist, it is 100% certain that ICANN would find some other organization to continue offering .de nameservice. Maybe this definition should use a name other than critical infrastructure. And my suggestion is nothing more than a first draft. My main point is that a new policy proposal should begin with a first draft of the policy itself so that people can discuss the draft policy instead of spending all the time discussing why it is impossible to write a policy at all. --Michael Dillon
