Summary

Tunisia · AI-generated

isp residential government tunisia

ATI-TUNIXP is operated by Agence Tunisienne d'Internet (ATI), the principal public internet service provider in Tunisia.

What it's used for

  • The address space carries residential and business internet access, evidenced by the reverse DNS record cimspmail20.outgw.tn and the registrant ATI LIR DEP on the 197.10.250.0/24 block.
  • The AS announces 768 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

  • The registrant ATI LIR DEP on 197.10.250.0/24 aligns with the AS holder, while the other two prefixes list unknown registrants.
  • ATI was created in 1996 and is run by the Ministry of Communications, serving as the main ISP for the country.
  • The inventory consists of three /24 blocks, all located in Tunisia, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
