A university lаb's discоvery ledger shоws thаt 10.41.7.88 аppeared in DHCP lease histоry for three days, responded once to ICMP, never completed a TCP handshake, and has no current ARP entry. A student wants to delete it as a phantom host. A second address, 10.41.7.89, has the same vendor OUI, similar hostname pattern, and a current SSH banner. The lab migrated several instruments last week and sometimes reuses addresses from a small pool. Evidence packet: the DHCP lease for 10.41.7.88 was issued to MAC A on Monday and expired Wednesday; 10.41.7.89 currently resolves to MAC B on the same switch rack; the migration ticket says one instrument NIC was replaced but does not record which address was reused. The inventory tool can merge, preserve as separate with issue flags, or suppress stale records from analyst view. Select all recommendations that should survive review.
