About this network

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.
