Summary
QTS (Quality Technology Services)
hosting legacy
QTS is Quality Technology Services, LLC, a United States data-centre operator providing colocation, hyperscale, and connectivity services.
What it's used for
- Data-centre and colocation address space: customer-facing hosted infrastructure plus the network services QTS layers on top of its facilities.
- The addresses sit in data centres, so they behave as hosting space rather than as end-user or corporate space.
Notable
- QTS operates a large portfolio of U.S. data centres and serves hyperscale cloud tenants as well as traditional colocation customers.
- The company was taken private by Blackstone in 2021, having previously traded publicly as QTS Realty Trust.
Interesting
- Colocation ASNs are a good place to watch address space change hands: what is announced from a data-centre network shifts as tenants move in and out, in a way an enterprise or university ASN never does.

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: 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.
