And so some do not. More or less the same situation as with the new fibre companies here in Europe. Anyway, I say it can not be denied that the IPv4 exhaustion will have an effect on Fidonet.

Some providers require a business account for static address. Some offer business accounts to all customers, some require proff that one actually runs a business, by showing a registration with the chamber of commerce. A business account ususally is more expensive.

Trick or not, it makes sense to me. From the POV of the ISP. The fibre companies have cheap bandwith to spare, but IPv4 addresses are scarse and expensive. So they try to nudge their customers in that direction...

Fidonet sysops being in the remaining group.

All of the fibre companies here except one now offer IPv6. For free.

Thank you for you contibution.


Cheers, Michiel
