Every registrar may have a slightly different method of actually implementing an A Record change. You can always contact their support system if you need help.

Generally, you’ll have to find the DNS, Host or Zone records for your domain and change the A Record IP address to the one below:

209.124.66.18

Once the A Record is updated, it can take between 24 and 48 hours for the new settings to propagate across the Internet.

Note: If there is an A record for the www entry, you may need to update it to the IP address above also. If you have a cName record for www, that should be fine.
