Work order WO-2614 · Larkfield Community Library

You're the junior network analyst at Larkfield Community Library. Lead admin Priya Okonkwo is replacing the edge firewall this weekend and signed a scope agreement authorizing you to inventory the library's own public service subnet first — so the new ruleset doesn't accidentally cut off a live service. Your job: find which hosts are up, record the services they expose, and stay strictly inside the authorized range.

In scope (authorized)198.51.100.0/24

Privacy: use a pseudonymous callsign — this lab collects no real names, emails, or IDs. Your callsign maps to your real identity only in your instructor's separate roster.
Integrity: the checklist and answer key live in this page and are self-reported; the screenshot and server timestamp are supporting evidence, not proof.
