United States · AI-generated

hosting transit infrastructure

Its IPv6 announcements form a doubling ladder, each prefix twice the size of the one before, all the way from /46 to /38.

What it's used for

  • A hosting and network services provider. 11,264 addresses across 14 IPv4 prefixes plus 15 IPv6 prefixes, with two observed BGP neighbours.

Notable

  • The sampled IPv6 prefixes climb in a chain under 2404:1200: two /46s, then a /45, /44, /43, /42, /41, /40, /39 and /38.
  • Blocks carry HIQPLATFORM-V4-5 and HIQPLATFORM-V4-8, registered to Internap Holding LLC.
  • 72.5.160.0/23 carries the netname PNAP-09-2004, a date in the label.
  • Four blocks carry INTERNAP-SG-AGILE1, INTERNAP-SG-AGILE2 and PNAPSG-SG-001, registered through a Singapore entity with a HorizonIQ Network Engineering contact.
  • Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

  • A doubling ladder is what a router produces when it splits a large allocation into the smallest number of pieces that can cover a range with a hole in it. Each step doubles because binary addressing leaves no other option, and the result reads like a staircase.
  • Three brand names appear across the records: the AS name, an abbreviated platform prefix on the netnames, and a network engineering contact under a fourth name. Each rebrand added a layer without removing the one below.
  • Announcing IPv4 from four continents' worth of ranges under one AS is what a provider does when it sells the same service in many facilities.

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 1,778 prefixes, as published 2026-10-20. 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.
