Unclassified APNIC
Summary
Atos Bilişim (Turkey)
enterprise legacy
SBS-AS2 is held by Atos Bilişim Danışmanlık ve Müşteri Hizmetleri Sanayi ve Ticaret A.Ş., the Turkish arm of the IT services group Atos, based at Yakacık Cad. in Kartal, Istanbul.
What it's used for
- IT outsourcing and managed services for Turkish enterprise customers. The AS announces
212.133.128.0/18plus one more-specific /24 — roughly 16k IPv4 addresses — and is single-homed, with just one observed BGP neighbour. That is an end-site/managed-services footprint, not a carrier.
Notable
- The
SBSin the handle is Siemens Business Services. Atos absorbed Siemens IT Solutions and Services in 2011, and the AS handle was never renamed — a fossil of the previous holder rather than anything to do with the current name. - The
A.Ş.suffix is anonim şirket, the Turkish joint-stock company form. It is a corporate suffix, not a network term. - No IPv6 is announced.
- No reverse DNS is delegated on the announced space — the
in-addr.arpazones under133.212return no nameservers at all, so the /18 is dark in reverse rather than merely missing PTRs. Unremarkable for corporate and client-facing systems that are reached by forward name, but it does mean there is no direct evidence of what the block carries: the classification rests on the holder, theATOS_MAIN_NETregistration and the single-homed end-site shape.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
