Summary
Brightbox Systems
business vpn uk small
BRIGHTBOX-AS is operated by Brightbox Systems Ltd.
What it's used for
- The address space carries corporate infrastructure, evidenced by reverse DNS entries like
cip-109-107-36-0.gb1.brightbox.comand netnamesUK-BRIGHTBOX-20100420andUK-BRIGHTBOX-20120918. - The AS announces 5120 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 4 observed neighbours, indicating a small-scale business network rather than a transit or large access provider.
- Traffic consists of internal corporate endpoints and services for the Leeds-based company, which operates as a private limited company with a small employee base.
Notable
- Registrants for both announced prefixes are listed as "Brightbox Admin; Brightbox Systems Ltd", matching the AS holder.
- The inventory is compact, consisting of one /20 and one /22 block, consistent with a single-site corporate estate.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, 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 1,779 prefixes, as published 2026-10-22. 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.
