[44net] Dumb question - 44.130 IP address?

One kind question, first of all, after a forced break due to changing my home address and various other reasons not to be discussed here I had to learn my IP adresses assigned to me long ago and that I used for a long time ago are no longer existing. OK, maybe I can understand the reason for that. Now I'm searching for that "portal" to register myself for getting a new IP assignment for being able to start playing with Amateur Radio Packet applications and so on, so I search for the portal. Well, there is a portal. But that portal is not showing up at all when you try to contact it. Does that mean you have to have an IP to register for an AmPR IP, but no wait - I just want to register for it? Can you please enlighten me what is going on here? I just don't understand it right now. Thanks, Wolfgang
