Summary

Dina IT Solutions SA

Switzerland · AI-generated

business it-services switzerland

CISEL is the AS handle for Dina IT Solutions SA, a Swiss IT services provider formed from the merger of Cisel and neo technologies.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by the netname CH-CISEL-20171215 and registrant Dina IT Solutions SA for the primary block.
  • With 1280 IPv4 addresses announced across 2 prefixes and 41 observed neighbours, the ratio indicates a transit or peering-heavy role rather than a large-scale access network.
  • Traffic from this AS consists of business data for clients utilizing cloud, security, and SAP integration services, as well as internal corporate connectivity for the Dina group.

Notable

  • Registrants align with the announcer for the primary prefix, while the secondary prefix 195.141.249.0/24 is registered to sunrise ip registry under the netname SUNRISE-NET, suggesting leased or inherited space from Sunrise.
  • The operator is the result of a merger between Cisel and neo technologies, rebranded as Dina to combine their IT expertise in Switzerland.
  • The inventory is small and finely subdivided, consistent with an internal corporate estate or a boutique IT service provider rather than a mass-market ISP.

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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
