Network Discovery

Combined discovery — ping-sweep + 20-port probe + reverse DNS in one pass — with two post-sweep routes for what to do with the results.

How it runs

Point it at a CIDR. ShellYard:

1. Parallel ICMP sweep across every host in the range
2. For each responder, probes 20 common TCP ports
3. Resolves reverse DNS (PTR) on every IP that responded

Each row shows IP, hostname (if reverse DNS resolved), open ports, MAC address (where ARP can resolve it), and response time.

Optional nmap enrichment

Toggle Enrich with nmap before the sweep and ShellYard runs nmap -O against responders to fill in OS class, vendor (from MAC OUI), and a deeper port list. Adds time per host; toggle off for large CIDRs.

Two routes after the sweep

Add Missing to Connections

Select rows, click Add to Connections. A wizard opens per row:

1. Probe — verifies the host is still reachable
2. Confirm — set the connection type (SSH / RDP / Telnet) and folder
3. Save — connection is created with the probed metadata pre-filled
4. Optional also import to IPAM — drops the same host into an IPAM subnet after the connection saves

Good for “I just landed at a new client and need to capture their environment fast.”

Add to IPAM only

Skip the wizard. Selected rows drop straight into an IPAM subnet document as child hosts. Hostname, MAC, and open-port summary populate automatically.

Good for “I have an existing IPAM doc and just want the live state captured.”

Tier behavior

Available on every tier — no gating. IPAM writeback requires the Documents feature (Team+).
