• exact course of actions depends on the registrar you're using, but generally you must have an A record somewhere that says:

  www.somename.com. IN A 1.2.3.4
  

  you need to change that so that it reads:

  www.somename.com. IN A 4.3.2.1
  

  it also possible the www is a CNAME to another domain that has an A record. But all that you can find out from the company that you registered your domain with. ask them, or if they have web console - doi it yourself, to change the IP from server A to server B.
