Summary
Agence Tunisienne d'Internet (ATI)
government isp legacy
ATI-TN — the Agence Tunisienne d'Internet, Tunisia's state internet agency and the operator of the country's national IP backbone.
What it's used for
- National backbone and upstream connectivity for Tunisian ISPs, universities and public institutions, along with hosting and domain services run by the agency.
Notable
- A government network in the truest sense: ATI is a public agency, and for years it was the mandatory international gateway through which essentially all Tunisian internet traffic passed.
- That chokepoint position made ATI the technical instrument of national filtering under the pre-2011 regime, a role widely mocked at the time as "Ammar 404". The agency was restructured after the 2011 revolution and the filtering apparatus dismantled.
Interesting
- A single agency holding both the national backbone and the country's early ASN is a common shape for states that brought the internet in through one door in the mid-1990s.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
