education university research

CSM-AS is operated by Colorado School of Mines.

What it's used for

  • The address space is registered under the netname CSM-NET for the Colorado School of Mines, a public research university in Golden, Colorado.
  • The AS announces 65536 IPv4 addresses within a single /16 prefix (138.67.0.0/16) and maintains only 1 observed neighbour, indicating a self-contained institutional network rather than a transit provider.

Notable

  • The RDAP registrant Colorado School of Mines aligns directly with the AS holder name.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a standard on-campus infrastructure footprint.

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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
