Summary

Deerfield Academy

United States of America · AI-generated

education business us

DEERFIELD-ACADEMY is operated by Deerfield Academy.

What it's used for

  • The address space carries the internal network of a private secondary school, with all three prefixes registered under the netname DEERFIELD and registrant Deerfield Academy.
  • The AS announces 1792 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or access provider.
  • Traffic from this AS consists of staff, students, and administrative endpoints within the school's campus infrastructure.

Notable

  • All registrants for the announced prefixes are Deerfield Academy, matching the AS holder and confirming a single-organisation estate.
  • The inventory is finely subdivided into three contiguous IPv4 blocks within the 208.92.240.0/22 range, reflecting internal segmentation for a single site.

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 1,783 prefixes, as published 2026-10-17. 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.
