Hello, I am working on removing IPv4 from our AD DC machines, so they operate with only IPv6. I have removed the machine's IPv4 addresses. It is no surprise, though, that the IPv4 address still appears in Samba DNS (can be seen when running 'samba_dnsupdate --verbose'). I am aware of the documentation for changing an AD DC's IP address[1], but I could not find documentation regarding removing an IP address. Q: How do I remove the old IPv4 address from Samba DNS (and possibly other places)?

(note that I say 'want' not 'need') Do you have more than 2,147,483,647 computers, printers, scanners etc ? Are you doing something like connecting your AD directly to the internet ? If you really must do this, you will need to create an IPv6 reverse zone, then add the IPv6 addresses for your computers etc to this zone. Then you will have to modify? 'dns_update_list' to only use IPv6, then find all IPv4 addresses in AD, ensure that an IPv6 address exists for it and delete the IPv4 address and finally remove the IPv4 reverse zone. Rowland

(note that I say > 'want' not 'need')I want to do this because IPv4 is a legacy protocol. I do not need IPv4, it is old, and I do not want IPv4 in my network if I don't need it.> Do you have more than 2,147,483,647 computers, printers, scanners etc ?No.> Are you doing something like connecting your AD directly to the internet ?Yes.> Then you will have to modify ?'dns_update_list' to only use IPv6, then > find all IPv4 addresses in AD, ensure that an IPv6 address exists for it > and delete the IPv4 address and finally remove the IPv4 reverse zone.Thank you.> Rowland-- To unsubscribe from this list go to the following URL and read the instructions: ?https://lists.samba.org/mailman/options/samba
