education business us

MHCC-AS001 is operated by Mt. Hood Community College.

What it's used for

  • The address space carries legacy infrastructure, with netnames CENTURYLINK-LEGACY-QWEST-INET-114 and CENTURYLINK-LEGACY-QWEST-INET-115 and reverse DNS entries pointing to chyn.qwest.net.
  • The AS announces 768 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit provider.

Notable

  • The registrants for both announced prefixes are listed as CenturyLink Communications, LLC, which differs from the AS holder, Mt. Hood Community College.
  • The address inventory consists of two distinct IPv4 blocks: 63.230.190.0/23 and 65.100.48.0/24, with no IPv6 prefixes in the inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
