Summary

Bridgestone Europe

Belgium · AI-generated

business corporate internal

BRIDGESTONE-EUROPE-AS is held by Bridgestone Europe NV.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames FR-FIRESTONE and Bridgestone registered to Bridgestone Europe NV.
  • The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and services for Bridgestone's European operations, including logistics and tire manufacturing.

Notable

  • Registrants align with the announcer, with both prefixes registered to Bridgestone Europe NV.
  • The address inventory is minimal, consisting of two /24 blocks, consistent with a corporate estate segmented for internal use.

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 1,782 prefixes, as published 2026-10-16. 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.
