We're about to open a small office and have obtained a domain name from Network Solutions for our email. We are going to use our local phone company's DSL service. When the DSL modem arrives, are they going to provide me with IP addresses and DNS addresses which somehow need to be pointed to Network Solutions? Or is it the reverse, do I change some address in my account at Network Solutions so the emails go from them to my DSL/ISP? There are all kinds of warnings on Network Solutions site that if I change things that my email may not work, etc.
