You can actually add wavelength zone subnets; however there IS a bug (see my annoyingly auto-closed "stale" issue at #864) that doesn't allow this to work if using IPv6/dualstack at all because WLZ doesn't do IPv6 and it breaks the module.

[ForbiddenEra]

Bump before stale again, reminding that my issue #864 was closed, I can't re-open and I don't really want to create a new one for it and this is kinda related.

[ForbiddenEra]

I think #892 could be considered as a potential way forward for handling subnets; if not exactly how suggested there, at least improving the flexibility should be considered especially in cases like this where one wants to use WLZ and IPv6 together or otherwise.
