I know exactly where the costs are and I am planning to configure my businesses accordingly. The IPv6 part is just a bolton to the Mesh callsign registry I am already building. I can throw a /62 at every registrant with no hassle. 1) The Mesh Foundation, a not-for-profit runs the registry as public goods. Sells blocks of 10,000 Mesh registrations for $100 each to anyone who wants to set up a Mesh Service Provider (MSP) or just issue registrations. 2) Threshold Secrets, a for profit MSP that provides customer service, account hosting etc. at commercial rates. The big difference between my model and the traditional Internet account model is that accounts are portable. You own your account, it is bound to the public keys you own. So you can register with my MSP, use it for a year, decide you don't like the service I provide and switch to Fred's. That change is advertised through the registry. All the costs of the registry are offloaded onto the MSPs. VeriSign sheds the cost of customer service to the registrars. I am proposing to shed the cost of resolution service as well. So if I want to contact you on Signal, SMTP, etc. via your Mesh callsign (@christian), my client goes to my MSP, and finds the location of your current MSP servicing the account and presents an authenticated request for your current contact info. If authorised, your client gets my current contact info (or the contact info you are allowed, if I don't know you, its probably just info on how to request a contact exchange). I expect the operating expenses of the registry to be in the low seven figures operating at scale. If I am incorrect, we raise the rates. If we raise the rates higher than people find acceptable, we will get competition. > So a DoS attack would merely swell the coffers of the not-for-profit Mesh > foundation which will pay for development of code, etc. > > I am not sure that a Sybil attack is relevant as there is absolutely no > accreditation going on here except between the registry and the small set > of chosen peer notaries.

And I am asking* for a /32 from which I will allocate /62s so, I have room for 2^30 registrations in my initial allocation. If I start to run out, I ask for an extra /32. There are 16 million /32s in that space. So we don't run out till we have allocated a trillion registrations. And these are densely packed.

Since my plan is to add this to a registration service, I will be allocating in dense blocks with a transparent allocation rubric.
