museum business internal us

HMNS is the autonomous system for the Houston Museum of Natural Science.

What it's used for

  • The space carries internal museum infrastructure, evidenced by reverse DNS entries like NAT_Pool_064.hmns.org and the netname HMNS-V4.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix with only 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The RDAP registrant for the announced prefix 192.44.70.0/24 is explicitly listed as Houston Museum of Natural Science, matching the AS holder.
  • The address inventory consists of a single /24 block and a /48 IPv6 prefix, representing a modest footprint typical of a large institutional site.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-24, 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 1,779 prefixes, as published 2026-10-24. 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.
