Summary

Delo

Slovenia · AI-generated

media business slovenia

DELO-AS is operated by Delo Casopisno Zaloznisko Podjetje d.o.o.

What it's used for

  • The address space carries the corporate network for Delo, a Slovenian integrated multimedia company offering digital and print media, as indicated by the netname DELO-SI and registrant DELO Casopisno Zaloznisko Podjetje d.o.o.
  • The AS announces 512 IPv4 addresses in a single /23 prefix and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, web/API endpoints, and internal corporate services for the media organization.

Notable

  • The registrant DELO Casopisno Zaloznisko Podjetje d.o.o. matches the AS holder, confirming consistent ownership.
  • The Slovenian holding company FMR has owned Delo media since 2015.
  • The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, typical of a corporate network.

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 1,783 prefixes, as published 2026-10-20. 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.
