Summary

Iskra Transmission

Slovenia · AI-generated

business industrial slovenia

The AS handle ISKRATR-AS is held by Iskra Transmission d.o.o.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname ISKRA-TRANSMISSION-DD-SI and registrant ISKRA, d.o.o.
  • With 256 IPv4 addresses and 1 IPv6 prefix announced against only 2 observed neighbours, the ratio indicates a small, self-contained business network rather than a transit or access provider

Notable

  • The registrant ISKRA, d.o.o. aligns directly with the AS holder name, confirming consistent ownership
  • The inventory consists of a single /24 IPv4 block and one /48 IPv6 prefix, representing a compact internal estate typical of a specific corporate site or division

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: 440 networks and 1,773 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.
