Summary

New Jersey State Library

United States of America · AI-generated

government library education network

The AS handle NJ-STATEWIDE-LIBRARY-NETWORK is held by New Jersey State Library.

What it's used for

  • The address space carries the network infrastructure for the New Jersey State Library and its associated statewide library network, as indicated by the netname NJ-STATEWIDE-LIBRARY-NETWORK and registrant New Jersey State Library.
  • The AS announces 8192 IPv4 addresses across 5 prefixes with 4 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.

Notable

  • All registrants for the announced prefixes agree with the announcer, consistently listing New Jersey State Library as the registrant and NJ-STATEWIDE-LIBRARY-NETWORK as the netname.
  • The address inventory is finely subdivided into five prefixes within the 209.212.0.0/16 range, reflecting internal segmentation of the library's network estate.

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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
