Reboot AV

Show Network — DHCP Launcher

One action on this master Mac hands your chosen private range to every device set to DHCP — nothing installed on any client. Set the network below, generate the script, run it, and watch devices land on your range. Close the window to stop and restore.

Network settings

Interface (your show NIC)

Subnet base

Master / gateway IP

Netmask

Range start

Range end

DNS (optional)

Lease (sec)

Generated script — reboot-shownet.command

To run (one time):
1. Download it (button on the left) — it lands in your Downloads.
2. Open Terminal and run: bash ~/Downloads/reboot-shownet.command
3. Enter your Mac password when asked (it needs admin to set the interface + run the DHCP server).
4. Devices set to DHCP / "obtain automatically" now pull an IP in your range. The window shows them live.
5. Close the window / Ctrl-C to stop the DHCP server and put the interface back to DHCP.

⚠ Run this only on an isolated show network (your own switch), never on an office/venue LAN that already has a router handing out DHCP — two DHCP servers fight. Truly static-only gear (some consoles/switches) still needs a one-time manual set or its vendor tool; DHCP can only serve devices that ask.
