Summary

MAC TV s.r.o.

Slovakia · AI-generated

broadcasting media slovakia

SK-JOJ-ASN is held by MAC TV s.r.o.

What it's used for

  • The address space carries infrastructure for a Slovak television broadcaster, as indicated by the netname SK-JOJ-NET and the registrant MAC TV s.r.o.
  • The AS announces 256 IPv4 addresses in a single /24 prefix and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider
  • Traffic from this AS consists of internal corporate systems, broadcast infrastructure, and web endpoints for the television network

Notable

  • The RDAP registrant for the announced prefix matches the AS holder, confirming consistent ownership
  • The address inventory is minimal, consisting of a single IPv4 /24 and one IPv6 /48, typical for a media company's internal network

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
