Summary

The Computer Company

Netherlands · AI-generated

business netherlands ipv4 ipv6

The AS handle TCC is held by The Computer Company B.V.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to thecomputercompany.nl and the netname NL-TCC-20140212.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate endpoints and services for The Computer Company, a Dutch firm operating in computer consultancy and facilities management.

Notable

  • Registrants align with the announcer, listing TCC The Computer Company B.V. and TCC RIPE MANAGEMENT for the primary prefix.
  • The address inventory is compact, consisting of a single /22 IPv4 block and a single /29 IPv6 block, consistent with a private corporate network.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
