Summary
Molson Coors Beverage Company
business corporate beverage internal
AS-MOLSONCOORS is held by Molson Coors Beverage Company.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by the consistent netname
MCBCacross all four announced IPv4 prefixes. - The inventory consists of 1,792 IPv4 addresses spread across 4 prefixes, with 3 observed routing neighbours; this low neighbour count relative to the address block indicates a private corporate estate rather than a transit or access provider.

Notable
- All registrants for the announced prefixes are listed as Molson Coors Beverage Company, matching the AS holder and confirming direct ownership of the address space.
- The address inventory is finely subdivided into three /23 blocks and one /24 block, a structure typical of site-by-site segmentation within a large corporate network.
- Molson Coors Beverage Company is a Canadian-American multinational drink and brewing company, formed from the merger of Molson and Coors, and is the fifth-largest brewer worldwide by beer volume.

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 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
