About this network

Five prefixes inside one /22-sized neighbourhood, all of them a bank's own.

What it's used for

• Corporate networking for a Turkish bank. 2,304 addresses across five IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• Every block sits in 217.169: a /22, a /23 and three /24s.
• Three carry the dated netname TR-AKBANK-20010327; two are the undated TR-AKBANK.
• The registry contact on all five is Akbank IT.
• The AS handle is AKNET-AKBANK.
• Fifteen addresses were sampled and none returned a name.

Interesting

• Five separate announcements from one contiguous neighbourhood is deaggregation by a network that could announce far less. Splitting adjacent space into pieces is how an operator steers traffic — different pieces to different upstreams, or a piece kept routable when the rest is withdrawn — and for a bank with two providers it is most likely about controlling which one carries what.
• The dated and undated netnames mark two filing eras under one holder. 20010327 is precise to the day; TR-AKBANK is what the same organisation's records looked like before the registry started stamping them.
• Two upstreams and 2,304 addresses is a bank's public edge: branches, cash machines and customer-facing services need to be reachable from anywhere and to survive losing a provider. Everything genuinely sensitive sits behind that on addresses the internet never sees.
