Summary

Bloomington Public School District (ISD 271)

United States · AI-generated

education k12 legacy

The network of Bloomington Public Schools, Independent School District No. 271 in Bloomington, Minnesota, operating under the handle ISD271.

What it's used for

  • Campus and administrative networking for a K-12 public school district serving roughly 10,000 students across its schools.

Notable

  • An institutional (public school) network, not a commercial ISP or host.

Interesting

  • ARIN allocated AS1087 in 2022, so this low number is a recent reassignment and carries no early-internet pedigree.

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 1,843 prefixes, as published 2026-11-02. 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.
