Summary
Center for Educational Leadership and Technology (CELT)
enterprise education legacy
The network of the Center for Educational Leadership and Technology (CELT), an education-focused consulting and technology firm based in Marlborough, Massachusetts.
What it's used for
- Corporate networking for an organization that advises school districts, education agencies, and foundations on aligning leadership, learning, and technology.
- A small end-user network, not a service provider.
Notable
- Despite the "education" in the name, this is an organizational network rather than a university campus — addresses belong to a consultancy serving the education sector.
- The address footprint is modest, consistent with a single-office professional-services organization.

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 1,782 prefixes, as published 2026-10-16. 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.
