Summary

REXE Teknoloji A.S

Turkey · AI-generated

hosting business turkey

REXE is operated by REXE Teknoloji A.S.

What it's used for

  • The address space carries mixed registrants, including TR-HIZLI-20081008 for HizliNet Teknoloji A.S., net-CESYO for Superonline Iletisim Hizmetleri A.S., and TR-HIZHOSTING-20191125 for CNC BILISIM HIZMETLERI.
  • The AS announces 1280 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale hosting or enterprise network rather than a transit provider.
  • Traffic from this AS consists of dedicated server hosting and enterprise infrastructure, as REXE Teknoloji provides dedicated servers using modern data center infrastructure in Turkey.

Notable

  • Registrants do not fully align with the announcer; HizliNet Teknoloji A.S. and Superonline Iletisim Hizmetleri A.S. hold significant portions of the announced space, suggesting leased or historical allocations.
  • The address inventory is fragmented across four distinct IPv4 prefixes and one IPv6 prefix, with no single block dominating the announcement set.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, 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.
