Hi, @JoelMcKinnon. Note, we are not a domain registrar. There is more about this in the community support guide below:
So, you will still need a registrar for your custom domains. You can use Netlify DNS or keep using the registrar’s DNS (aka “external DNS”), both work for sites hosted at Netlify. There are instructions for both methods below:
Regarding the domain name you mentioned, planetandsky.com
I see that registered with wildwestdomains.com and not he.net:
$ whois planetandsky.com | egrep -i "^registrar"
Registrar WHOIS Server: whois.wildwestdomains.com
Registrar URL: http://www.wildwestdomains.com
Registrar Registration Expiration Date: 2021-03-01T02:24:56Z
Registrar: Wild West Domains, LLC
Registrar IANA ID: 440
Registrar Abuse Contact Email: abuse@wildwestdomains.com
Registrar Abuse Contact Phone: +1.4806242505
So, to be honest, I’m not entirely sure what role he.net plays in hosting your sites. It is hard to say what you need to do regarding that hosting service without knowing what services they are providing you currently. Would you be willing to please tell us more about how you currently use their service?
