dig  noall  answer @f.root-servers.net . AXFR

Available via AXFR:

dig  noall  answer @$(dig  short ns arpa. | head -1) arpa AXFR

This zone can also be walked using NSEC discovery.

Per inquiry to https://www.educause.edu/, the zone is only made available "when the proposed use of the zone file directly contributes to the security of the domain."

Inquiries should be sent to [email protected].

Per inquiry to the technical contact listed in WHOIS, the data for mil. is not made available.

DNS zone data is available for the generic TLDs per ICANN requirements via their Centralized Zone Data Service at https://czds.icann.org/.

Most gTLD operators provide this data without much push back. Some gTLD operators require you to submit an explanation of why you require access, others require you to submit some personal information (e.g., contact information, postal address, associated IP addresses), and yet others ask to see your ID.

Lastly, ICANN publishes monthly registry reports for the TLDs under its purview with a three month delay at https://www.icann.org/resources/pages/registry-reports/.

Per inquiry to [email protected], the zone for int. is not available to the public.

You can apply for Zone File Access on the upu.int website:

https://www.upu.int/en/Universal-Postal-Union/Activities/Digital-Services/-POST-Domain/Zone-file-access

The form itself is available on ICANN's website:

https://www.icann.org/en/registry-agreements/post/post-agreement-appendix-3--zone-file-access-agreement-11-12-2009-en

ccTLDs are not covered by the ICANN requirement to make zone data available to the public. When contacted, most ccTLD operators deny the request.
