About this network

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 212.64.204.0/22 and single /24s at 212.64.194.0, 197.0, 198.0, 200.0, 203.0, 209.0 and 220.0.
• Five carry the netname TR-ATLAS-990420.
• Three are TR-NAC-TELEKOM, registered to NAC Telekomunikasyon Sistemleri Limited Sirketi, with Atlas On-Line Network Management recorded 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 212.64.194 to 212.64.220 without 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.
