Summary

Adzibadem Sistina Skopje

North Macedonia · AI-generated

healthcare business private

The AS handle SISTINA-ASN is held by Adzibadem Sistina Skopje, a private clinic hospital in North Macedonia.

What it's used for

  • The address space carries the hospital's internal network, identified by the netname MT-AdzibademSistina and registrant MKT ADMIN; MKT ABUSE.
  • The AS announces 256 IPv4 addresses across 1 prefix (62.162.116.0/24) with 0 IPv6 prefixes.
  • With only 1 observed neighbour, this is a small, single-site corporate estate rather than a transit or access network.

Notable

  • The registrant MKT ADMIN; MKT ABUSE aligns with the hospital's operational identity, distinct from the general ISP infrastructure listed in secondary sources.
  • The inventory consists of a single /24 block, indicating a compact, self-contained network footprint typical of a private medical facility.

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: 455 networks and 1,849 prefixes, as published 2026-11-14. 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.
