Summary
Bandwidth
voip telecom enterprise cloud
VOXBONE-AS is operated by Voxbone SA, a Belgian telecommunications company that rebranded to Bandwidth.
What it's used for
- The address space carries VoIP and cloud communication services, evidenced by netnames
BE-VOXBONE-20060620andBE-VOXBONE-20140214registered to Voxbone SA. - The AS announces 5120 IPv4 addresses across 2 prefixes and 17 IPv6 prefixes, with 8 observed neighbours, indicating a role focused on enterprise connectivity and service delivery rather than bulk residential access.
- Traffic from this AS consists of voice media, signalling, and API endpoints for global enterprise networks, supporting the operator's business as a cloud communication platform.
Notable
- Registrants for both announced IPv4 prefixes are listed as Voxbone SA, consistent with the AS holder.
- Voxbone SA was acquired by Bandwidth, which now operates the network under the Bandwidth brand while retaining the original AS handle and registry identity.
- The inventory includes a large IPv6 allocation (
2a03:b500::/41) subdivided into multiple smaller prefixes, reflecting a modernized infrastructure supporting global service expansion.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
7 upstream, 0 downstream and 10 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
