Ah, it wasn't obvious that your AP was ZD managed in the inquiry.
If bringing up new APs in a production network, they will take local DHCP.
If this is not the VLAN/subnet the ZD is in, we recommend DHCP option 43/DNS
hostname resolution to point them, or you may need to use 'set director ip a.b.c.d'.

If bringing up/upgrading APs prior to ZD/AP deployment and not on a network,
you can temporarily use the built-in DHCP server (max scope 512 IPs).
If trying to bring up multiple new APs on a defaulted non-network ZD (192.168.0.2),
the first AP (default IP 192.168.0.1) will join, but all other APs after the first will not.
