Summary
Bellevue School District
education government infrastructure
Sixty-five thousand addresses for a school district, first announced in 2007.
What it's used for
- A public school district's network. A single IPv4
/16announced from the United States, no IPv6, and two observed BGP neighbours.
Notable
- The block is a
/16, the largest allocation size in common use, held by a district rather than a university or a carrier. - Routing history for this number begins in 2007, well after allocations of that size had become hard to obtain.
- The netname compresses the district's name by dropping vowels from both words.
- The registrant and AS handle both carry the district's number, and the registrant includes a hash character before it, which few registry fields contain.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- A district on this scale runs a network per school, and the allocation makes sense if every classroom device was expected to have its own address. That expectation was reasonable when the space was requested and looks generous now.
- One route for the whole thing keeps the district's internal structure private. Nothing in the routing says which range belongs to which school.
- Publishing nothing in reverse is the right default for a network full of children's devices. There is no operational reason for outsiders to resolve a school laptop's address to a building.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-23. 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.
