Local and External domains

our local domain matches our external domain. As we are having our website hosted outside, I created a static host record for www and put the external IP of our hosting company in our primary DNS zone.  Is there a better way to do this dynamically

    According to Microsoft this is the way it must be done:

    "Internal clients may be able to resolve resources on the internal domain, however, queries to external resources of the domain are not resolved by the DNS server. For example, if the internal network namespace is configured by using the publicly registered domain name of, only resources that have "A" (Host) records in the forward lookup zone for are available to local clients. This behavior can pose a problem if hosts resources, such as, a web server by means of an external provider or Internet service provider (ISP). Any queries from internal clients to are resolved as a negative query by the local DNS server because the "A" record for "www" does not exist in the forward lookup zone for For clients to access external resources, "A" records must be added to the forward lookup zone of the DNS server for those resources."

    The only other alternative is to use External DNS servers from your ISP, but that could cause other problems internally.
