Summary

Tez Tour (SINUM CURRUS LTD)

Cyprus · AI-generated

enterprise legacy

TEZTOUR-AS is the corporate network of Tez Tour, a large tour operator and travel company. The ASN is held by SINUM CURRUS LTD, a Cyprus-registered entity, and its contact addresses still point at teztour.com.

What it's used for

  • Corporate connectivity and public-facing systems for the travel business: booking and reservation platforms, back-office systems, and company infrastructure. This is an enterprise network, not a service provider.

Notable

  • Reverse DNS confirms the identity independently: routers in the block resolve under teztour.com, including a switch named for the M9 carrier hotel in Moscow, one of the region's main interconnection points.
  • The RIPE record lists a mix of regional upstreams and a small customer set, so the network is multi-homed but announces only a couple of small blocks.
  • The name is a genuine match to the travel brand, not a lookalike; the Cyprus holding entity is the registrant of record rather than a different company.

Interesting

  • The ASN's registry description carries a machine-readable verification token, the kind used to prove control of a resource on address-management platforms.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
