If you are using the 1&1 name servers (DNS), you can change the DNS settings (DNS zones, DNS records) such as the A record. The A record is the DNS record that holds which IP address the domain should point to. By default, this will point to the IP address for your 1&1 hosting package.
Log in to the 1&1 Control Panel using your Customer ID OR domain name and your password.
|US Control Panel||CA Control Panel|
If you have only one package, you will land on the Administration page. If you have more than one package, select the package in question to reach its Administration page.
Click Manage Domains from the Domains panel.
Click the arrow icon next to the domain name in question to display an options menu.
Select Edit DNS Settings from the Domain Settings section of the options menu.
If the domain is not currently set to use the 1&1 name servers, you will not be able to change the IP address within the 1&1 Control Panel. You will need to update the IP address with your current DNS host.
Select Other IP address and enter 126.96.36.199 within the text boxes. Each number separated by a dot(.) should be typed into a separate text box.
Click the Save button when finished.
A confirmation page is displayed informing you that the changes will be updated accordingly. As with all DNS changes, it may take up to one hour before the changes are recognized by all servers/computers on the Internet.
