Unclassified ARIN
Summary
Hawaii Department of Education
government education k12
The AS handle HAWAII-DEPT-OF-EDUC is held by the Hawaii Department of Education.
What it's used for
- The address space carries the network operations for the state's public education system, with all registrants identified as "Hawaii Dept. of Education; Network Operations Center" under the netname
HAWAIIDOE. - The AS announces 65536 IPv4 addresses across 14 prefixes while maintaining only 1 observed neighbour, a ratio that indicates a self-contained internal corporate estate rather than a transit or access network.
Notable
- All registrants in the pack agree with the announcer, consistently listing the Hawaii Department of Education as the holder.
- The address inventory is finely subdivided into 14 distinct prefixes ranging from /17 to /24, reflecting site-by-site segmentation typical of a large government agency managing multiple facilities.

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.
