Summary

Heliacal Networks

United States of America · AI-generated

business enterprise fiber

The AS handle HELIACAL is held by Heliacal Networks.

What it's used for

  • The address space carries enterprise and fiber infrastructure, evidenced by netnames HELIACAL-V4-1, HELIACAL-EUROPE, and MCKAYCOM-FIBRENET.
  • The AS announces 1536 IPv4 addresses and 6 IPv6 prefixes while maintaining only 4 observed neighbours, a ratio that indicates an access or enterprise network rather than a transit provider.

Notable

  • Registrants generally align with the announcer, with Heliacal Networks listed for the primary blocks, though 193.107.205.0/24 is registered to Robert McKay under the netname MCKAYCOM-FIBRENET.
  • The address inventory is small and fragmented, consisting of three distinct IPv4 prefixes and a set of IPv6 blocks, with one prefix specifically designated for European operations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, 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 2026-10-23. 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.
