Eight scattered fragments of one /19, three of them belonging to another company.
What it's used for
- Internet access in Turkey. 2,816 addresses in eight IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.
Notable
- The announcements are
212.64.204.0/22and single/24s at212.64.194.0,197.0,198.0,200.0,203.0,209.0and220.0. - Five carry the netname
TR-ATLAS-990420. - Three are
TR-NAC-TELEKOM, registered to NAC Telekomunikasyon Sistemleri Limited Sirketi, withAtlas On-Line Network Managementrecorded as the contact. - First seen in routing data in October 2001, a real date rather than the floor of the archive.
- Eighteen sampled addresses were queried and none returned a name.
Interesting
- The eight blocks sit inside a range spanning
212.64.194to212.64.220without filling it. The gaps are not accidents of aggregation; they are other people's addresses. What survives here is the pattern of a range that was divided among several Turkish providers in 1999 and has been trading hands ever since. - The NAC blocks invert the usual arrangement. Instead of this network's addresses being registered through somebody else's membership, another company's addresses are announced here with this company named as the operator. Whoever holds the paperwork and whoever runs the routers are separate questions, and the registry answers only the first.
- Eighteen addresses sampled and not one has a name. For a provider selling access, that is the customer's side of the network showing: addresses are handed out, not published.

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 2026-10-21, 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: 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.
