Summary

San Marino Unified School District

United States of America · AI-generated

education k12 network

SANMARINOUSD is operated by San Marino Unified School District.

What it's used for

  • The address space carries the district's internal network, identified by the netname SMNET and registrant San Marino Unified School District.
  • The AS announces 1024 IPv4 addresses within a single prefix (206.220.76.0/22) and maintains 1 observed neighbour, indicating a small, self-contained educational network rather than a transit or large-scale access provider.
  • Traffic consists of staff, student, and administrative endpoints for the district's schools, including San Marino High School, Huntington Middle School, and Carver Elementary School.

Notable

  • The RDAP registrant San Marino Unified School District matches the AS handle and the announced prefix netname SMNET.
  • The address inventory is a single contiguous /22 block, typical for a municipal or educational entity managing its own IP space.

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.
