  • Need to resolve external domain although zone is internal

    Hi there,

    Not the best at DNS so please bear with me.

    We have DNS on 2012 server with several zones. One of the zones we added: domain.co.uk is required to resolve several A records internally however, we have a sub domain: abc.domain.co.uk which is hosted by AWS. If our internal users try to access abc.domain.co.uk via a web browser it will result in 'Page cannot be displayed' which presumably because it tries to resolve through this zone. If I delete the zone it will work once I flush dns on my machine. So I guess what I am asking what is the method (if any) to force abc.domain.co.uk externally?

    Any guidance would be greatly appreciated.

    Have you put a record for abc (IP pointing to AWS) inside your domain.co.uk internal domain?
    (That assumes you want one record only)
    If you need more than one, create a new DNS zone abc.domain.co.uk and put in records - I have just tested this and they resolve OK

      Thank you Ossian,

      Think I was overlooking the simple method you suggested. We need the the abc.domain.co.uk zone for various SRV records and no doubt this will grow. As you suggested I created A record with abc created in abc.domain.co.uk zone with external IP which resolves fine.

      Thanks again much appreciated.
