Summary

Datapark

Switzerland · AI-generated

residential fiber isp switzerland

DATAPARK is operated by Datapark EKT AG.

What it's used for

  • The address space carries residential fiber-to-the-home services, evidenced by reverse DNS entries such as ftth-175-254.tbwil.ch and ftth-250-000.tbwil.ch.
  • The AS announces 26,880 IPv4 addresses across 9 prefixes and 2 IPv6 prefixes, while maintaining 116 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a regional access provider with significant peering relationships.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing "Datapark Network Operation Center" and "EKT AG" for netnames like CH-DATAPARK-20000407 and CH-DATAPARK-20210816.
  • The address inventory is subdivided into multiple /21 and /22 blocks, reflecting a segmented internal estate for different service regions or acquisition periods.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
