Summary

Sauk Valley Community College

United States · AI-generated

education enterprise

Every address sampled came back named as a DHCP lease, numbered by the two octets that identify it.

What it's used for

  • A community college's network. 4,096 addresses in a single IPv4 prefix, one IPv6 prefix, and one observed BGP neighbour.

Notable

  • The block is 108.59.144.0/20, netname SVCC-EDU, registered to the college.
  • All three sampled addresses returned a name, of the form dhcp-148-000.svcc.edu.
  • Each name pads the final octet to three digits, so dhcp-151-255 and dhcp-148-000 line up.
  • The IPv6 prefix is 2620:103:4000::/44.

Interesting

  • A whole /20 named as one DHCP pool is a campus where the addresses belong to people rather than to services. Laptops and phones arrive, take a lease, and leave, and the name describes the slot rather than whatever is currently sitting in it.
  • Padding the octet to three digits is what makes the names sort into address order in any tool that handles them as text, which matters when the list is read by staff chasing a machine on a network with thousands of transient devices.
  • Four thousand addresses for one college is generous by current standards and unremarkable for the era the block came from. Institutions that took space early kept it, and campus networks are one of the few places where every device still gets a public address.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
