Changing your domain's name servers can allow another hosting company to manage your domain's DNS settings.
To change your domain's name servers, login to your Lycos Domains account and click My Domains. From there, click on the domain for which you would like to change name servers.
Then click "Name Servers" in the left sidebar to get to the page for editing your domain's name servers.
Click "Use external name servers", and enter in up to 4 name servers, one per field. Then click Save.
Note that name server changes can take between 24-48 hours to take effect.
