Summary

ADVENTURECK

United States of America · AI-generated

business leased us

The AS handle AS26187 is held by ADVENTURECK.

What it's used for

  • The address space carries diverse small-business entities, with netnames including AL-3126, HGC GLOBAL COMMUNICATIONS LIMITED, GRACEWOOD-INTERIORS, ELIZABETH, JOERENDELL-LLC, and HUDGEN.
  • The AS announces 1536 IPv4 addresses across 6 prefixes and maintains 8 observed neighbours, a ratio consistent with a small-scale access or business network rather than a transit provider.

Notable

  • Registrants vary significantly from the announcer, including GlowNourish, GraceWood, Betsy Miller LLC, Joerendell LLC, and HUDGEN LLC, suggesting the address space is leased or allocated to multiple distinct entities.
  • The inventory consists of six /24 blocks, all located in the United States, with no IPv6 prefixes announced.

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: 436 networks and 1,769 prefixes, as published 2026-10-13. 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.
