In search for free domain I got IPQuick.
It gives a random domain for any IP4&6.
I know not reliable for commercial use but I just want a domain for nextcloud,fediverse and mail.
Questions
1.Is not IP keeps changing in short time will I need to Keep generating domains?
2.Any one using it?
Assuming that you mean that you are using the domain name to point to services which are at a residential, dynamic IP address, you will need to set up a Dynamic DNS service.
If a product is free, you’re the product.
