AS8685 DORUKNET

DorukNet (DORUKNET, legally *Doruk İletişim ve Otomasyon Sanayi ve Ticaret

A.Ş.*) is one of Turkey's oldest commercial internet companies, founded in 1993,

and today runs datacentres in Istanbul, Ankara, Antalya and Çorlu.

What it's used for

• Corporate internet access, colocation, cloud and — very visibly in the rDNS — web and email hosting. Sampled names land on dorukcloud.com virtualisation hosts, web2.webkontrol.doruk.net.tr shared-hosting servers, and mail-relay clusters (mtaNN.smrtmsg.com).
• Business customer assignments are named directly: Turkish company domains appear on individual /24s, which is what a B2B access provider's space looks like.
• Generic filler is rev.A.B.C.D.doruk.net.tr, and one sub-allocation is registered to Acronis's Turkish entity.

Notable

• ~43,000 IPv4 addresses split into around 170 announcements, almost all /24s. That looks scattered at first glance, but it is not a brokered inventory: the /24s are slices of a handful of contiguous DorukNet blocks (in 212.2, 212.58, 213.155, 82.151, 81.21, 94.102), all registered to DorukNet in the RIPE database under one maintainer, all with first-party rDNS.
• There is no residential naming anywhere — no dialup, DSL, PPPoE or dynamic pools — despite DorukNet having been an early Turkish consumer ISP. The business today is hosting and corporate connectivity.
