I have no idea what forum this belongs in so i decideded to post it here to be safe

i brought a domain name from crazydomains.co.nz and i want to make it so that when i visit my domain it resolves to my ip address.

i've tried using a service called free dns but that didnt seem to work and now when i browse to my domain name, instead of going to my server it goes to some web page saying i've shared it (i did no such thing)

i changed the name servers on my crazydomains.co.nz account back to how they were when i got it but i imagine that takes time to propagate throughout the internet.

i have DDWRT on my router and assumed i'd be able to use one of the in built dynamic dns services on there but they all seem pretty dodgy looking money grabbers so i decided to ask here before i do anything else.

my domain name is haamfish.co.nz and from my internet connection it resolves to crazydomains.co.nz's homepage, but on my mobile data connection it resolves to a freedns.afraid.org website saying i've shared it.
