Summary

Emerson College

United States · AI-generated

education business infrastructure

Most of the college's space belongs to a carrier, under a netname naming a different range.

What it's used for

  • A college network. 9,216 addresses across two IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

  • 199.94.64.0/19 holds nearly all the space and is registered to a carrier, netname LVLT-ORG-199-92.
  • That netname names a range two higher in the second octet than the block it sits on.
  • 172.99.212.0/22 is netname EMERSON-US-V4-01, registered to the college, naming the institution, a country, the protocol version and a counter.
  • 199.94.87.254 answers as 87-254.dhcp.emerson.edu, carrying the last two octets and marking the address as dynamically assigned.
  • Three upstreams serve the campus.

Interesting

  • A college announcing a carrier's block as its main range means the space leaves if the contract does. The smaller block the college holds outright is the part that survives a change of provider, and it is a twentieth of the size.
  • Marking an address as DHCP in its reverse name tells a reader the machine behind it changes, which is useful for abuse handling and equally useful to anyone deciding which addresses are worth watching.
  • Naming the protocol version in a netname reserves room for a second, which has not arrived.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
