    Hi all,

    Today, I just had a big discussion with AD design team:
    they propose that our internal domain name should be xy.net and our
    compnay's external domain name is xy.com. I just wonder why use xy.net for
    internal domain name and we should use xy.local for our internal domain name
    to seperate internal and external domain even though xy.net is not registered.

    Can anyone help me out?

    Thank you.

  2. Hello ed,

    The internal/external domain name shouldn't be equal as this require additional
    configuration for DNS. On example is a webpage that is accessible from the
    internet with www.domain.com, internal without additonal configuration you
    can't open it that way.

    If you don't have an external domain name yet, it doesn't matter how you
    name it. But i assume your AD design team is thinking about the future and
    their recommendation is quite correct, to better separate the external and
    internal domain name. The TLD that you use internal shouldn't be able to
    be registered in the public. This reduces some configuration and problems
    like the webpage example.

    Best regards

    Meinolf,

    Thank you for your help.

    I mean why the design team recommend to use xy.NET for our INTERNAL domain
    name and why do we just use xy.LOCAL for our internal domain and totally
    seperate internal and external DNS name as you mentioned too. Here is my
    reasoning that xy.net can be registered in Public DNS though nobody registers
    xy.NET yet. (We already registered xy.com for our external domain name and
    this is right. ) I am talking about why using xy.net for INTERNAL domain
    name?

    thank you.

  4. Hello ed,

    It is not important which one you use for the internal domain name. If it
    is registered it will still have a different ip address and no DNS registrar
    should use your public ip address for that name, so even if someone use the
    xy.net all requests for that domain name will be linked to the other companies
    ip address.

    Personal i would not use a TLD that is able to be registered in the public
    at the moment. But as long as the name is registered with another companies
    ip address, it shouldn't matter for your internal name.

    Best regards

    Hello, Ed,

    The domain name choice could have been made either by a personal
    choice because the team was comfortable with it, or by some other
    choice. Hard to tell. Either way, as Meinolf said, whichever you
    choose there are pros and cons with either name.

    I created a blog on this, link posted below. I hope you find it
    informative.
