dynDNS registrations are suspended

I have just unboxed my shiny new Nextbox and got as far as trying to set up remote access via the Guided Dynamic DNS function, however it looks like desec is currently not allowing new domain registration as per deSEC – Free Secure DNS

Is there an alternative available?

Thank you.

Ignore me please for now. Turns out that’s not the problem at all, it’s our router that is ancient and doesn’t do port forwarding as expected: https://www.reddit.com/r/HomeNetworking/comments/3tcs3w/port_forwarding_on_huawei_hg659b/
