Summary

Air Serbia

Serbia · AI-generated

airline corporate serbia

JAT-AS is the autonomous system for Air Serbia a.d. Beograd.

What it's used for

  • The space carries corporate network traffic for the airline, identified by the netname JAT-Net and registrant Air SERBIA a.d. Beograd.
  • The AS announces 512 IPv4 addresses within a single prefix (91.194.216.0/23) and maintains 3 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate communications, office workers, and operational systems for the airline's headquarters and hub at Belgrade Nikola Tesla Airport.

Notable

  • The registrant Air SERBIA a.d. Beograd agrees with the announcer, confirming the space is owned by the airline.
  • The operator was formerly known as Jat Airways and was renamed and rebranded as Air Serbia in 2013.
  • The address inventory is a single /23 block, consistent with a dedicated corporate allocation for a major national carrier.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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: 442 networks and 1,778 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.
