Summary

connecta ag

Switzerland · AI-generated

isp regional switzerland cable

KNSURSELVA is the AS handle for connecta ag, a regional telecommunications provider operating in the Surselva region of Switzerland.

What it's used for

  • The address space carries infrastructure for local utility and energy providers, evidenced by netnames such as CH-EWZERNEZ-20180619 (EW Zernez), CH-EWSAMNAUN-20180622 (EW Samnaun), and CH-EWD-20180222 (EWD Elektrizitaetswerk Davos AG).
  • The inventory includes 15,104 IPv4 addresses across 10 prefixes and 5 IPv6 prefixes, with 50 observed neighbours, indicating a role as a regional access or transit provider connecting local entities.

Notable

  • Registrants include Connecta Network Engineering Team; connecta ag for the largest blocks, while smaller blocks are registered to specific local utilities like EW Zernez and Mia Engiadina Network SA.
  • Two prefixes (64.239.60.0/23 and 193.186.252.0/24) are registered to Meinl Internet Commerce GmbH and IPAG TECH, suggesting leased or historical space not directly related to the primary Swiss utility operations.
  • The address inventory is a mix of large /20 blocks for the main operator and smaller /22 and /24 blocks for specific local partners, reflecting a fragmented but regionally focused deployment.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
