OBC Networking
## network
Spectrum brings internet in via coax to their modem. The modem feeds the Eero
(acting as gateway, handing out 192.168.4.0/24). Downstream of the Eero is the
old Spectrum router still emitting an SSID on 192.168.1.0/24 — needs turning
off (requires Spectrum admin access).
## printer
The printer was originally self-assigned static IP 192.168.1.165. After
switching to Eero DHCP (192.168.4.0/24), it now gets 192.168.4.25. The admin
desktop has a static rule configured for it, but the port config on the desktop
still had the old 192.168.1.165 address — had to update it to point to
192.168.4.25. The port name is stuck as IP_192.168.1.165 (couldn't be changed).
The DHCP-assigned 192.168.4.25 is subject to change — need to iron that out.
