Summary

Advania Sverige AB

Sweden · AI-generated

business it-services sweden

CORE-TELECOMPUTING-SE is held by Advania Sverige AB.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname MEKONOMEN-PI-NET associated with registrant Mekonomen AB.
  • The AS announces 256 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and services for Advania Sverige AB, a major IT service provider in Northern Europe.

Notable

  • The registrant Mekonomen AB differs from the AS holder Advania Sverige AB, reflecting the historical acquisition of Mekonomen by Advania.
  • The inventory consists of a single /24 IPv4 block and a /32 IPv6 block, representing a compact corporate estate.

Reputation

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
