Summary

Tigron

Belgium · AI-generated

business msp belgium

TIGRON-AS is operated by Tigron bv.

What it's used for

  • The address space carries corporate infrastructure, identified by netnames BE-TIGRON-1 and BE-TIGRON-20110325 registered to Tigron bv.
  • The AS announces 5,376 IPv4 addresses across 3 prefixes and 4 IPv6 prefixes, with only 3 observed neighbours, indicating a small-scale business network rather than a transit provider.
  • As an IT Managed Service Provider, the traffic consists of business clients, office workers, and managed IT endpoints.

Notable

  • Registrants for all announced prefixes are consistent with the announcer, listing Tigron bv and Tigron Hostmaster.
  • The inventory is compact, comprising a single /20 block and two smaller IPv4 blocks alongside a small set of IPv6 prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
