Unclassified ARIN
Summary
Bronco Wine
business enterprise infrastructure
Seven separate blocks from four providers, for one winery.
What it's used for
- A winery's network. 1,792 addresses across seven IPv4 prefixes, all of them small, with three observed BGP neighbours and no IPv6 announced.
Notable
- Three blocks are registered to the company under
BRONCO-W816-7,BRONCO-W21-12andBRNC-75-141-1-0; another under the full company name. - One is registered to
AT&T Services, Inc.asATTWORLD30and two toComcast Cable Communications, LLC, both asCCCH3-4. - Nine of eighteen sampled addresses answered. Some are the full address written with dots in front of the company domain, one is
sso.broncowine.com, and three carry a carrier's own template.
Interesting
- Seven blocks from four providers, none adjacent, is what a business network looks like when it grows site by site. Each facility bought whatever connection was available locally, kept the addresses that came with it, and the AS ties them together afterwards.
- The reverse names put the whole address in front of the domain rather than replacing the dots with dashes, which is unusual and means somebody wrote the zone by hand rather than generating it.
- Naming a single sign-on endpoint in public DNS points an outsider straight at the login page for the company's internal systems. It is a small piece of free reconnaissance and worth avoiding.
- Two of the seven records carry an identical netname under one cable provider, so those blocks cannot be told apart from the registry alone.

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 2026-11-04, 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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
