IPAM DNSsync IPAM prefix required ?

[lukts30]

Is there a way to make IPAM DNSsync behave as if the IPAM prefixes for the zones were set to cover the entire IPv4/IPv6 address space?

I am asking because Netbox itself does not allow such prefixes (0.0.0.0/0) to be set up. netbox-community/netbox#6825

For now I have both 0.0.0.0/1 and 128.0.0.0/1 assigned in the DNS View but that feels a bit silly.

So you are the one who is using up all the IPv4 prefixes after all :-)

Seriously: This is an issue with NetBox, as you noted yourself. Your IPv4 workaround, while looking a bit clumsy, is the only idea I would have come up with to work around this problem as well without a major change in NetBox DNS.

The main issue is that assigning one or more views to all prefixes that haven't an assigned or inherited does not cover the whole problem, as to get it right the views would need to be assigned to VRFs, not globally. This is even more problematic as the "Global" VRF isn't in fact a VRF object, it is the VRF assumed for all prefixes with None in their VRF field. It isn't impossible, but it's not trivial either and requires a whole lot of work and testing.

On the other hand, the advantage for the majority of users is pretty small IMHO, as in most cases only a finite number of prefixes are maintained in NetBox (and yes, I can imagine other scenarios, but I didn't personally encounter one of them yet). There are a couple of ideas where I think the effort is invested to benefit a larger number of users.
