Summary

National Student Clearinghouse

United States of America · AI-generated

education business nonprofit data

The AS handle NSLC-ORG is held by National Student Clearinghouse.

What it's used for

  • The space carries internal corporate infrastructure, evidenced by the reverse DNS record dlppolicy.studentclearinghouse.org and the netname UU-65-202-239.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (65.202.239.0/24) and maintains only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The RDAP registrant NATIONAL STUDENT CLEARINGHOUSE aligns perfectly with the AS holder and the reverse DNS domain.
  • The address inventory is minimal, consisting of a single contiguous /24 block with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,848 prefixes, as published 2026-10-31. 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.
