To edit your nameservers on one or several domains, you log in to your Customer Zone via MissHosting. Log in with your email address and password you chose when you purchased your domain through us.
Once logged into your customer zone, click on "Domains" in the left-hand menu and then "My Domains".
You will now see a view with all the domain names you have registered with us. Simply click on the arrow next to the button for the domain you wish to edit and click on "Manage Nameservers".
Now, you will see a view with nameservers. Remember to check the box for "Use custom nameservers", and then fill them in below.
So remember, the small button where it says to use custom nameservers should be checked if you're going to use other nameservers than Miss Hosting.
Once you've filled in your new nameservers, just click on "Change Nameservers" at the bottom, this will now take up to 24-48 hours before it works.
