Summary

Cubic Telecom

Ireland · AI-generated

mobile business legacy

An Irish company providing global mobile connectivity for connected vehicles and industrial equipment.

What it's used for

  • Machine connectivity across borders. 1,792 IPv4 addresses over four prefixes, eight IPv6 announcements, two observed BGP neighbours.

Notable

  • The IPv6 side is eight separate /43s and /44s scattered through 2a0b:39c0::/32 — 1010, 1020, 1070, 1100, 1120, 1190, 11a0 and 11c0 — with large gaps between them.
  • Three of the four IPv4 blocks are Cogent's, two of them named CUBIC-TELECOM-CGNT-NET-1 and -2 where CGNT marks the source.
  • Only 185.114.16.0/22 is the company's own, registered as IE-CUBIC-20150820.

Interesting

  • The gapped IPv6 layout is the interesting half. Announcing eight blocks with room left between them is how an operator grows each one later without renumbering, and for a business that assigns addresses per country, per manufacturer or per vehicle platform, keeping those groups apart in the address plan matters more than keeping the routing table small.
  • A connected car is a roaming device that never gets a new SIM and may outlive the network it was sold with. That makes address planning a fifteen-year problem rather than a quarterly one, which is a rare constraint and shows up here as an unusually orderly IPv6 layout next to a scrap of borrowed IPv4.

Reputation

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
