Summary

Terega

France · AI-generated

energy infrastructure france

TIGF-AS is operated by Terega SA.

What it's used for

  • The address space carries internal corporate infrastructure, identified by the netname TEREGA-NET in the RDAP records.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic consists of internal communications for Terega, a French natural gas transmission and infrastructure company.

Notable

  • The registrants for both prefixes are listed as Heliantis Admin; Abuse-C Role, which differs from the AS holder Terega SA, suggesting the address space is managed by a third-party administrator or reflects post-acquisition registry records.
  • Terega was formerly known as TIGF (Transport et Infrastructures Gaz France), a name change reflected in the AS handle TIGF-AS.
  • The inventory consists of two contiguous IPv4 blocks: 83.173.124.0/23 and 83.173.126.0/24.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
