Generally it is better to use 'internal.example.com.' instead of invented
TLDs like 'mytld.'.
FreeIPA can work with 'invented' TLDs if you have properly configured DNS
but it is usually a nightmare. That is the reason why it is strictly
Also, 'invented' TLDs cannot work with DNSSEC validation unless you
distribute trust anchor to every single DNSSEC validator. This is one more
reason for using proper sub-domains instead of invented TLDs.
Let me know if you want to hear mode details about that. Have a nice day!
