Summary

Glarner Kantonalbank

Switzerland · AI-generated

business banking enterprise

The AS handle GLKB is held by Glarner Kantonalbank.

What it's used for

  • The address space carries the bank's internal corporate network, identified by the netname GLKB-NET and registrant Glarner Kantonalbank.
  • The inventory consists of 256 IPv4 addresses in a single /24 prefix and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained enterprise network rather than a transit or access provider.
  • Traffic from this AS represents the bank's own operational infrastructure, including office workers, internal systems, and web/API endpoints for its banking services in the Canton of Glarus.

Notable

  • The registrant Glarner Kantonalbank matches the AS holder and netname GLKB-NET, confirming consistent ownership.
  • The address inventory is minimal, comprising a single IPv4 block and one IPv6 prefix, typical for a regional corporate entity.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
