About this network

AS9091 (SWEDBANK-AS) is held by Swedbank, one of the largest banking groups in Sweden and the Nordic/Baltic region.

What it's used for

This is enterprise infrastructure for a major bank, not a service-provider network. The AS announces a single 194.8.10.0/23 block (about 512 addresses) through one observed upstream, backing Swedbank's own internet-facing and internal systems.

Notable

The prefix has been announced since 2000. A single /23 with one upstream is the signature of a corporate network that multihomes purely to control its own routing rather than to carry customer traffic. No PTRs were returned on the addresses sampled, consistent with locked-down financial-sector infrastructure.

Interesting

Banks typically keep a small, tightly controlled public address footprint and push most services behind gateways; the minimal announced space here reflects that security posture.
