Summary
AtlantisNet
isp residential eyeball fiber
AtlantisNet (ATLANTIS-CENTRAL) is a Turkish fibre internet provider run by Atlantis Telekomünikasyon, selling GigaPON and VDSL/fibre home broadband to consumers across Turkey.
What it's used for
- Residential fibre and VDSL home internet, marketed with uncapped, no-commitment plans up to gigabit and multi-gigabit speeds.
Notable
- An "eyeball" network: addresses here are home internet connections, not servers, commonly behind carrier-grade NAT.
- A regional/independent ISP that resells over local telco infrastructure as well as its own GigaPON build, rather than a national incumbent.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 445 networks and 1,817 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.
