Summary

Advania Sverige AB

Sweden · AI-generated

business it-services enterprise

ITM-SE is operated by Advania Sverige AB.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by netnames SE-ADVANIA-20081215, SE-ADVANIA-20140520, and ITM-NETWORK registered to Advania Sverige AB.
  • The inventory consists of 6,400 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with 6 observed neighbours, indicating a business network with limited transit dependencies.
  • Traffic from this AS consists of internal corporate communications, web/API endpoints, and office worker connectivity for Advania's IT service delivery operations.

Notable

  • Registrants align with the announcer, with Advania Sverige AB listed for the majority of prefixes, though 193.180.206.0/24 is registered to Sveriges Lakareforbund under netname SE-LAKARE.
  • The AS handle ITM-SE reflects the company's historical identity as IT-mastaren Mitt AB, which was rebranded to Advania Sverige AB.
  • The address inventory is finely subdivided into four distinct IPv4 blocks, consistent with internal corporate estate segmentation.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
