Please add support for assigning ULA prefixes to VLANs (i.e. fc00::/7). There is a quasi-registry at [https://ula.ungleich.ch/](https://ula.ungleich.ch/). This could be expanded to support assigning any arbitrary prefix to a network, not necessarily just ULA. These prefix should co-exist with any DHCPv6-PD prefixes
