Summary

Northshore School District

United States of America · AI-generated

education business k12 us

NSD417 is operated by Northshore School District.

What it's used for

  • The address space is registered to the Washington School Information Processing Cooperative (WSIPC) under the netname WSIPC-NET, indicating this is a shared educational network resource.
  • The AS announces a single IPv4 prefix, 152.157.64.0/20, comprising 4096 addresses, with 2 observed routing neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit provider.

Notable

  • The RDAP registrant is the Washington School Information Processing Cooperative, which differs from the AS holder name Northshore School District, reflecting the cooperative structure of Washington state school networks.
  • The inventory consists of a single contiguous /20 block with no announced IPv6 prefixes.

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.
