# Host Cleanup

## Overview

Remove decommissioned/unused host configurations that are no longer reachable on the network.

## Hosts to review

The following hosts return "no route to host" from Prometheus scraping and are likely no longer needed:

- `media1` (10.69.12.82)
- `ns3` (10.69.13.7)
- `ns4` (10.69.13.8)
- `nixos-test1` (10.69.13.10)

## Steps

1. Confirm each host is truly decommissioned (not just temporarily powered off)
2. Remove host directory from `hosts/`
3. Remove `nixosConfigurations` entry from `flake.nix`
4. Remove host's age key from `.sops.yaml`
5. Remove per-host secrets from `secrets/<hostname>/` if any
6. Verify DNS zone and Prometheus targets no longer include the removed hosts after rebuild
