isp residential turkey

TTNETDC is operated by Yesilbir Bilisim Teknolojileri Bilgisayar Yayincilik Sanayi ve Ticaret Ltd. Sti.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries such as host-185-19-93-0.ttnetdc.com and host-2-56-60-128.ttnetdc.com.
  • The AS announces 4096 IPv4 addresses across 10 prefixes with only 1 observed neighbour, a ratio characteristic of an access network providing last-mile connectivity rather than transit.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints, consistent with the operator's role as a regional internet service provider in Bursa, Turkey.

Notable

  • All registrants in the RDAP data align with the announcer, listing Yesilbir Bilisim Teknolojileri Bilgisayar Yayincilik Sanayi ve Ticaret Ltd. Sti. as the holder for every prefix.
  • The address inventory is fragmented into small /23 and /24 blocks, including ranges like 185.19.92.0/22 and 2.56.60.0/23, reflecting incremental acquisition of address space over time.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 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.
