Summary
İşNet (Is Net Elektronik Bilgi Üretim Dağıtım Ticaret ve İletişim Hizmetleri A.Ş.)
isp enterprise legacy
ISNET is İşNet, a Turkish internet and telecom services provider established in 1999 and a subsidiary of İşbank (Türkiye İş Bankası).
What it's used for
Internet access and communications services aimed largely at corporate customers. Sampled reverse DNS is dominated by generic ptr-90-158-NNN-NNN.is.net.tr static-style naming plus VoIP hosts (mgcp-*.voiptest.is.net.tr), with no dsl/pppoe/dyn subscriber-pool markers, consistent with business/static assignments rather than a mass consumer eyeball pool.
Notable
A sizeable provider footprint across 90.158.0.0/90.159.0.0, 213.143.x, 212.98.x and other blocks. Live routing status was unavailable in the pack, but the prefix inventory and first-party is.net.tr rDNS confirm a genuine, self-operated Turkish ISP.
Interesting
Being owned by İşbank, İşNet grew out of a bank's IT/telecom arm into a commercial ISP and data-centre operator, which is why its addressing reads more corporate than residential.
