Summary
Los Angeles Public Library
government education legacy
LAPL-LAPUBLICLIBRARY is the AS of the Los Angeles Public Library, the City of Los Angeles department that runs Central Library downtown plus dozens of neighbourhood branches.
What it's used for
Branch networking for a public library system. RIS observes 7 IPv4 prefixes carrying 1,792 addresses, no IPv6, and a single BGP neighbour — one upstream, a handful of /24s, an institutional edge with no provider character at all.
Notable
The reverse DNS is the most informative part of the pack, because it shows the network split by function per branch. Sampled addresses resolve to names like ayosco-public.lapl.org and ayosco-staff.lapl.org, buscen-staff.lapl.org, hydepk-other.lapl.org and wifi-05.lapl.net — a branch code plus a role. That is a library system carrying two distinct populations on the same AS: staff and back-office systems on one set of addresses, public-access terminals and patron Wi-Fi on another. Addresses in the public/Wi-Fi role behave like a shared institutional guest network, which is worth knowing before treating any of this space as belonging to a single identifiable user.
Interesting
Two of the announced /24s (173.196.25.0/24, 173.196.27.0/24) still answer with biz.spectrum.com reverse DNS — the default naming of the upstream cable operator's business service, on space that the library nonetheless announces from its own AS. It is a clean illustration of the rule that rDNS shows what a block carries and who serves it, never who holds it: the same AS shows first-party lapl.org names on some blocks and its carrier's boilerplate on others.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,845 prefixes, as published 2026-10-31. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
