Summary

Yalniz Bilisim Teknolojileri

Turkey · AI-generated

hosting business turkey

YALNIZ is operated by Yalniz Bilisim Teknolojileri Tic. Ltd. Sti.

What it's used for

  • The address space carries hosting infrastructure, evidenced by reverse DNS entries pointing to rdns.renklihost.com and netnames such as net-yalniz-bilisim-teknolojileri-tic-ltd-sti and ML-1450.
  • The AS announces 1024 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web hosting and server endpoints for the operator's clients, consistent with the renklihost.com domain and the business nature of the registrant.

Notable

  • Registrants for the largest prefixes align with the announcer, listing yalniz bilisim teknolojileri tic. ltd. sti and YALNIZ BILISIM TEKNOLOJILERI TIC. LTD.STI., while one prefix is registered to Mobosoft and another to Oguzhan Yalniz.
  • The address inventory is small and fragmented across four distinct /24 blocks, suggesting a collection of leased or acquired ranges rather than a single contiguous allocation.

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.
