Summary

Ventures DC

Turkey · AI-generated

datacenter hosting business

The AS handle VENTURESDC is held by Ventures-DC Crestu Teknoloji Dijital Hizmetler Limited Sirketi.

What it's used for

  • The address space carries static datacenter infrastructure, evidenced by reverse DNS entries such as static-153.56.128.128.ventures.com.tr and netnames like VENTURES-DC-VERI-MERKEZI-HIZMETLERI.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 19 IPv6 prefixes, while maintaining only 2 observed neighbours, indicating a hosting or datacenter role rather than transit.
  • Traffic from this AS consists of web and API endpoints hosted within the Ventures DC datacenter facilities in Turkey.

Notable

  • Registrants align with the announcer, listing Crestu Teknoloji Dijital Hizmetler Limited Sirketi and Ventures DC Telekomunikasyon ve Bilgi Teknolojileri Sanayi ve Ticaret Limited Sirketi.
  • The address inventory is compact, consisting of two contiguous IPv4 blocks and a series of aggregated IPv6 prefixes under the 2a11:1fc0::/48 space.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
