Hosts

Hosts & Devices

The Hosts tab is a sortable, filterable table of every discovered or manually-added device — IP, hostname, MAC, vendor, type, open ports, last seen, plus a liveness dot (green online / red offline / grey unknown) and a static/dynamic badge.

Filter by text or by classification; click any column header to sort. Click a row to open the detail panel at the bottom (info, ports, services, changes, uptime, SSH).

Editing a host

Edit (from the detail panel) lets you set:

• IP address — yes, you can change it. It's a full rename: the host keeps its notes, ports, services, SSH access, history, and topology links, all cascaded to the new IP. Blocked if the new IP already belongs to another host (use Merge instead).
• Hostname, device type, vendor, OS, notes — typing a MAC auto-inserts the : separators.
• Device type — router, switch, server, nas, workstation, container, vm, camera, tv, ap, etc. Drives the topology node color and the status-page Networking grouping.
• Classification — Auto (from the subnet's DHCP range) or force Static/Dynamic.
• Gateway (Level 1) — marks the root of your network hierarchy.
• Alert opt-outs — don't alert on this host's MAC changes / offline-online (e.g. a phone with a randomized MAC).
• Show on public status page + a public name — see Public Status Page.

Static vs dynamic

Set a subnet's DHCP range (edit the subnet with the ✎ pencil). Hosts inside it classify as dynamic, outside as static. This scopes change alerts (you usually only care about static devices changing). Hosts outside every subnet, or in a subnet with no DHCP range, read as unknown.

Multi-homed devices (aliases)

A machine with two IPs? ⇌ Merge them so it shows as one host with alias IPs, instead of two separate rows.

Bulk actions

• Select all / tick individual rows → Delete selected to clear many hosts at once.
• Manually-added hosts are tagged manual until a scan confirms them (finds a MAC), then they become scanned.

Add a host manually

+ Add Host for something Boltarr can't scan (or hasn't yet). Useful for documenting devices before a scan, or things off-subnet.
