A DNS zone already exists on NS1 (on second registration on Netlify DNS)

Hi Netlify Support team,

I have an issue with adding domains to Netlify DNS. My domain name is tsekai.com .

When I’m trying to add this domain to Netlify DNS it gives A DNS zone for this domain already exists on NS1, the DNS provider backing Netlify DNS Please contact NS1 with the domain name for support.

Some more context: I have registered this domain on Google Domains. I’ve successfully added this domain to Netlify DNS before for a personal project on Netlify. However, later I changed the domain of that project to some other domain. Now, I’m trying to host a separate project on Netlify with this domain but I’m getting this error. Could it be that Netlify still has the NS1 zone of tsekai.com for my previous project?

I would appreciate it if you could help. Thanks.

Did you remove the domain from the project?
Did you remove the domain from the team (via the Domains page)?

Yes. tsekai.com is not in the Domain management section of the project nor the Domains section of team.

Hi @tsekai,

Thanks for reaching out and welcome to Netlify’s Support Forums!

NS1 is a DNS SaaS company. We use NS1 (https://ns1.com/) for DNS services at Netlify.

The reason for this error (“A DNS zone for this domain already exists on NS1”) is because some other company has already configured a DNS zone for this domain at NS1. Because it already exists, Netlify cannot create a new one.

We are not the only company that builds our services using NS1 as a component. For example, if I am not mistaken, Squarespace also uses NS1. If you configured this domain at Squarespace (or similar service) that will prevent us from doing the same.

There are two solutions for this.

The first solution for this will be to discover which other service you have used this domain with. Then contact that service to have them remove the configuration for this domain at NS1. That is the only solution which allows for using Netlify DNS for this domain name.

NS1 won’t tell us who the other company is that already configured this domain with their service. This means you will need to determine which other services you have used for DNS service for this domain and contact that company to get this removed.

There is another solution. Instead of using our Managed DNS, you can also use external DNS method for the custom domain at Netlify.

You can also start by using external DNS method for now while you work with the other company to remove the DNS configuration they already have at NS1.
