Network Inventory / Devices

VLAN profiles use base A.BA.B.<VLAN>.0/24. Pick Class A/B/C or Custom, and Print/PDF will stay consistent.
Company, Timestamp & VLAN Profiles Inventory
Auto-fills current time.
Saved locally in your browser.
Quick base
Pick A/B/C to auto-fill base. Custom lets you type any A.B you want.
Profiles use A.B.<VLAN>.0/24 (ex: 10.0.10.0/24).
Safe mode won’t overwrite custom subnets you typed.
VLANs: OFF
If OFF, device VLAN fields are locked off and VLAN Profiles are hidden.
“Allow” keeps the per-device VLAN Mode selector visible.
Option 2: OFF clears VLAN/VLAN Name for every device entry (Undo available).
Suggestions require selecting a VLAN Profile with a /24 subnet.
2–254
Default 10 keeps space for infra.
Comma list of host numbers to skip (per VLAN).
Tip: Pick Class A/B/C or Custom base — VLAN profiles and PDF stay consistent.
VLAN VLAN Name IPv4 Subnet Notes Actions
Tip: Keep subnets /24 if you want simple “next IP” suggestions.
Add a Device Assets
If “No VLAN”, VLAN fields are disabled and cleared.
Pick a profile VLAN, or choose “Manual VLAN…” to type one.
Only used if you choose “Manual VLAN…” above.
If you choose a profile VLAN, this fills. Manual VLAN = you type the name.
IP suggestions work only when a VLAN Profile is selected (with /24 subnet).
