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.
