Summary

dtms

Germany · AI-generated

telecom business enterprise

107 BGP neighbours on two prefixes, one of them acquired from another company in 2021.

What it's used for

  • A German telecommunications-services network. 8,448 addresses in two IPv4 prefixes, 107 observed BGP neighbours, and no IPv6 announced.

Notable

  • The inventory is 212.125.32.0/19 and 193.242.123.0/24.
  • The /19 carries the netname DE-LIT-19990705, registered to dtms GmbH.
  • The /24 is DE-NEXNET-20211122, registered to nexnet GmbH.
  • Six addresses were sampled and none returned a name.

Interesting

  • 107 neighbours against two prefixes is not a subscriber network; it is a network other networks connect to. Companies that handle call routing and number services need direct paths to a great many carriers, because the value of the service is the reach.
  • The two netnames are twenty-two years apart and name different companies. 19990705 is original allocation from the year the business started announcing; 20211122 is a block filed under another name and now announced from here. One inventory, two eras, two entities.
  • DE-LIT matches neither company's current name, which is the ordinary state of a twenty-five-year-old registry record. The netname preserves whatever the organisation called itself the day the paperwork was filed, and nothing in the system requires it to be updated.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
