Summary

Tismi

Netherlands · AI-generated

mobile telecom netherlands

TISMI is operated by Tismi BV.

What it's used for

  • The address space carries mobile network traffic, evidenced by the registrant Tismi BV and netnames such as NL-TISMI-20180622 and DE-TISMI-AS-20240409.
  • The AS announces 3328 IPv4 addresses across 4 prefixes and 19 IPv6 prefixes, while maintaining 1332 observed neighbours, a ratio indicative of a transit or peering-heavy role rather than a simple access network.
  • As a national telecom operator active in the Netherlands, UK, Switzerland, and Iceland, the traffic consists of mobile subscriber data and signalling.

Notable

  • Registrants for the largest prefixes are consistently Tismi BV, aligning with the AS holder Tismi Tismi BV.
  • Tismi BV was acquired by Link Mobility Group in 2021 for EUR 20 million.
  • The inventory includes a German-registered prefix 37.202.25.0/24 alongside Dutch blocks, reflecting the operator's multi-country presence.

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 1,771 prefixes, as published 2026-10-15. 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.
