Summary
Webair / Opti9
hosting cloud managed-hosting
An Autonomous System (WEBAIR-INTERNET-MTL) operated by Webair Internet Development Company, a Garden City, NY managed-hosting provider that rebranded to Opti9. The -MTL handle reflects its Montréal data-center presence.
What it's used for
- Managed public/private/hybrid cloud, disaster-recovery-as-a-service, offsite backups, and colocation across sites including New York, LA, Montréal, and Amsterdam.
Notable
- An IP here identifies Webair/Opti9 as the host, not the tenant running on it.
- Focused on managed and DR-oriented enterprise hosting rather than cheap self-service VPS.
Interesting
- Webair rebranded to Opti9 in 2022, consolidating its cloud, backup, and disaster-recovery services under the new name.

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 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,768 prefixes, as published 2026-10-12. 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.
