# Rack7 DNS and DHCP

`minio01` (10.77.42.31) serves DNS and DHCP for the whole lab shelf.

- dnsmasq answers port 53 with upstream `1.1.1.1` and `9.9.9.9`.
- VLAN 130 (lab-iot) pool: 10.77.130.50–10.77.130.200, 6-hour leases,
  netmask 255.255.255.0.
- Pi-hole runs on 10.77.42.53; the admin UI is on port 18553 behind
  caddy-rack7 and uses the blocklist `reese-abuse-v3`.
- VLAN 42 has no DHCP at all — every device there gets a static address.
