    Good day everyone. A have a question. My DNS seems to be working correctly but I noticed an issue that I can’t seem to find an answer to.

    If I run nslookup from any of my servers in the environment attaching an external DNS server to the lookup, it resolves the non-authoritative answer by appending my internal domain to the name and giving 127.0.53.53 as the address.

    Example:

    C:>nslookup http://www.google.com 8.8.8.8

    Server: google-public-dns-a.google.com
    Address: 8.8.8.8

    Non-authoritative answer:
    Name: google.com.internal.domain (where internal.domain is my internal domain)
    Address: 127.0.53.53

    The above nslookup resolves correctly if I do not enter a DNS server IP. It also doesn’t matter what external DNS IP I use in the lookup. They all resolve the same as above.

    Any ideas what the issue could be here?

    I setup Forwarders on both of my DNS (Domain Controller) servers leveraging my ISP external DNS servers and Google’s public DNS (8.8.8.8) as a third option. I also have all of my clients pointing DNS to my internal DNS servers.
