Summary

itm8

Denmark · AI-generated

business it-services denmark

JDM is the AS handle for itm8 A/S, a Danish IT services provider formed by the merger of 13 companies including JDM and IT Relation.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname ITM8-A-S-NET-JDM and reverse DNS entries like despec12.despec.dk.
  • The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and IT service endpoints for the itm8 group, which provides application services and IT consulting to business clients.

Notable

  • Registrants for both announced prefixes list itm8 A/S as the holder, aligning with the current corporate identity.
  • In November 2023, 13 companies including JDM, IT Relation, and AddPro Denmark merged to form itm8, consolidating their operations under a single entity.
  • The inventory consists of two /24 blocks, 91.238.212.0/24 and 193.104.43.0/24, with no IPv6 prefixes announced.

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 1,784 prefixes, as published 2026-10-19. 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.
