Summary

St Erik Kommunikation

Sweden · AI-generated

business sweden corporate

The AS handle STEK-AS is held by St Erik Kommunikation AB.

What it's used for

  • The address space carries corporate infrastructure for the City of Stockholm, evidenced by reverse DNS entries such as winmedia.itc.edu.stockholm.se, ppjobbtorg.stockholm.se, and jobbistan.stockholm.se.
  • The network announces 4096 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 20 observed neighbours, indicating a role focused on internal corporate connectivity rather than large-scale residential access.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing S:t Erik Kommunikation AB as the administrative and technical contact under the netname SE-STOKAB-20000929.
  • The address inventory consists of four contiguous IPv4 blocks within the 217.21.224.0/21 range and a single /32 IPv6 prefix, reflecting a finely subdivided internal 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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
