The admin port of a 1990s Instant Internet appliance, and nmap's deslogind label.
IANA registers 3006 as ii-admin, "Instant Internet Admin" — the management port of the Instant Internet branch-office internet appliance line (Performance Technologies, later Bay Networks/Nortel). Nmap labels it deslogind, the daemon side of the deslogin tool sitting one port above 3005. Both are historical; the appliances are decades out of service and nothing current is expected here.
Do not expose
Both candidate identities are unauthenticated-era admin planes on unsupported software — anything genuinely serving them should be off the network, not firewalled.
