A1MK-AS43612 is operated by A1 Makedonija, a telecommunications provider in North Macedonia.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries like ctel-92-53-16-0.cabletel.com.mk and netnames such as MK-A1-INTERNET and MK-ONEVIP-MOBILE.
  • The AS announces 27,392 IPv4 addresses across 15 prefixes and 1 IPv6 prefix, with 10 observed neighbours, indicating an access network serving end-user connections rather than a transit hub.
  • Traffic from this AS consists of subscriber eyeballs using cable and DSL services for internet access, video streaming, and general web browsing.

Notable

  • All registrants in the RDAP data align with the announcer, consistently listing "A1 Makedonija" or "Company for communications services A1 Makedonija DOOEL Skopje".
  • A1 Makedonija is owned by the A1 Telekom Austria Group, which operates telecommunications networks across Central and Eastern Europe.
  • The inventory includes a mix of legacy and newer allocations, with netnames referencing both "A1" and "ONEVIP", reflecting the company's history of brand consolidation and network expansion.

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 1,773 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.
