Registration
Where you bought the domain. This is where you renew it, set the nameservers and get the transfer code.
Free domain check
Type your domain name. You see in one go where it is registered, where your DNS runs, where your website and your mail are hosted, and so where you need to log in to change something.
You bought your domain from one party, your website is with another, your mail is with Microsoft or Google, and the DNS may run somewhere else again. If you change a record in the wrong place, nothing happens.
Where you bought the domain. This is where you renew it, set the nameservers and get the transfer code.
Where the nameservers point to. Changes to A, CNAME, MX and TXT records only work there.
Where the A record or the CNAME points to: the server that shows your site.
Where the MX records point to, and whether SPF and DMARC are set up correctly so your mail does not end up in spam.
At Netslim, your domain, DNS, website and email live in one account, with one invoice. Transferring is free and your site and email keep working: we copy over your existing records.
First check where your DNS runs: changes only work there. If that is correct, you just have to wait: old answers stay until the TTL expires, usually an hour, sometimes a day.
The registrar is where you bought and renew the domain. The DNS is the address book that says where your website and email are. Often this is the same party, but not always. In that case you only set the nameservers at the registrar, and the records themselves somewhere else.
Many hosting providers buy domains through a wholesaler. In that case, the party that sends you the invoice for the domain is the one you need to go to.
This means we don't recognize the network of the IP address by a known name. The IP address is shown next to it. Your host can tell you whether it is their server.
We only read public data: the registry and the DNS, just like every browser and mail server does. We don't store anything of what you look up, except the result for ten minutes for speed.

The chat goes along to WhatsApp, so you don't have to repeat anything.
