About this network

ANADOLUBANK-AS is the corporate network of Anadolubank A.Ş., a Turkish commercial bank headquartered in Istanbul and part of the Habaş group. The AS exists to give the bank its own multi-homed presence rather than to sell anything.

What it's used for

• The bank's own internet edge: internet banking, mail and other public-facing services. The rDNS that is delegated points straight at the bank's own domain, for example mail.anadolubank.com.tr.
• Multi-homing across Turkish carriers so that branch and online-banking access survives a single upstream failure.

Notable

• A classic enterprise profile: roughly 768 IPv4 addresses across three small prefixes, a couple of BGP neighbours, no downstream customers and no subscriber pools. Nothing here is sold as connectivity.
• Banks are one of the most common categories of small enterprise AS holder. Regulatory expectations around availability and the need to keep DR sites reachable make provider independence worth the administrative overhead, even at this tiny address footprint.
• The address space should be geolocated to the bank's own Istanbul infrastructure, not treated as consumer or hosting space.
