Summary

Ozkula Internet Hizmetleri

Turkey · AI-generated

hosting business turkey

The AS handle OZKULA is held by Ozkula Internet Hizmetleri Tic. LTD. STI.

What it's used for

  • The address space carries hosting and business infrastructure, evidenced by reverse DNS entries such as dns-cesrey.com and vm.kogo.com.tr, and netnames referencing Cesrey Bilisim Teknolojileri Anonim Sirketi.
  • The AS announces 1024 IPv4 addresses across 3 prefixes with only 2 observed neighbours, a ratio that indicates a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web hosting endpoints and virtual machines, consistent with the operator's provision of affordable hosting services.

Notable

  • Registrants include Alastyr Telekomunikasyon A.S. for the largest prefix and Cesrey Bilisim Teknolojileri Anonim Sirketi for the remaining prefixes, indicating the space is shared or leased from these entities.
  • The inventory consists of three distinct IPv4 prefixes with no IPv6 announcements, reflecting a small, fragmented address estate.

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: 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.
