Summary

SIX Group

Switzerland · AI-generated

enterprise finance legacy

SIX is held by SIX Group Services AG, the Swiss financial-market infrastructure

operator that runs the SIX Swiss Exchange and Switzerland's interbank clearing and

payment systems.

What it's used for

  • Corporate and financial-market infrastructure networking for the exchange, clearing, settlement and securities-data businesses of the SIX Group.

Notable

  • No PTRs on the addresses sampled, and only 2 observed neighbours, consistent with a tightly controlled private financial network rather than a public ISP.
  • Announces ~10k addresses across 10 IPv4 prefixes plus IPv6; a single-institution enterprise network, not a commercial host or carrier.
