About this network

Nine prefixes carved from one range, eight of them sharing a single 1999 netname, with router loopbacks answering in DNS.

What it's used for

• A Turkish internet and hosting provider in Istanbul. 8,192 addresses across nine IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• Every block sits in 212.109: a /20, two /22s, two /23s and four /24s.
• Eight of them carry the same netname, TR-TICARETNET-991129; 212.109.98.0/24 is the odd one out at TICARETNET.
• Twelve of eighteen sampled addresses returned names, all of the form lo0.tho116.ticaretnet.com and lo254.tho123.ticaretnet.com.
• First observed in the routing archive at the earliest date the archive holds.

Interesting

• lo0 and lo254 are loopback interfaces: the addresses a router answers to regardless of which physical link is up. Naming them in public DNS is a working convention rather than an oversight, because an operator tracing a path wants to read a router's name instead of an address. It also means the reverse zone is a partial map of the network's own equipment.
• 991129 is a two-digit year, November 1999. Two other holders in this range carry two-digit November 1999 netnames, in Poland, and one in Italy is dated that December. The registry's format change can be dated from the paperwork of networks that had nothing else in common.
• One /20 announced alongside eight smaller blocks from inside the same range is deaggregation: the space could be advertised as a couple of routes, and instead it is advertised as nine. Usually that means different parts are handled differently, and the routing table carries the cost of the distinction.
