The netnames are not names. They are address ranges, written out with a space and a hyphen in the middle.

What it's used for

  • A provider's network. Ten IPv4 prefixes announced from Mexico, no IPv6, six thousand four hundred addresses, through one observed BGP neighbour.

Notable

  • Every netname is a pair of addresses separated by spaces and a hyphen, marking the first and last of a range. Most registry netnames are labels; these are coordinates.
  • Several blocks carry their parent's range rather than their own, so different blocks show the same netname over different addresses.
  • The registrant is the provider on most blocks, but its name is written two ways: once with the full corporate form and once with a word missing from the middle.
  • Two blocks belong to other companies. One names a firewall, a country and a facility, joined by an underscore where every other field uses hyphens. The other is the same sort of corporate name, punctuated with initials and full stops.
  • Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

  • A netname holding an address range is what a registry produces when the field is generated from the allocation rather than written by a person. It is accurate, unreadable, and impossible to search for by name.
  • Announcing ten separate prefixes through a single upstream means the fragmentation buys nothing in routing terms. The pieces exist because they were allocated that way.
  • One field naming a firewall is the only functional description in the record, and it belongs to somebody else.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 prefixes, as published 2026-10-15. 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.
