AS5606 — GTS-BACKBONE GTS Telecom

AS5606 announces 102 IPv4 prefixes covering 91,648 addresses and 4 IPv6 prefixes.

About this network

GTS-BACKBONE is the backbone AS of GTS Telecom SRL, the Romanian operator of the former GTS Central Europe group, headquartered on Strada Izvor in Bucharest. Deutsche Telekom acquired GTS Central Europe in 2014, and GTS Telecom has been part of the Deutsche Telekom group since.

What it's used for

Business-grade connectivity in Romania: IP transit, fibre and cross-border capacity, VPN services and data-centre hosting, delivered over GTS's own network and direct interconnects with tier-1 carriers. Roughly 92,000 IPv4 addresses.

Notable

This is a corporate carrier rather than a consumer ISP — the customer base is companies and institutions, so addresses here generally front business sites and hosted infrastructure. The RIPE object still publishes a 24x7 NOC contact, a small tell of a network run for enterprise SLAs.

Interesting

The Czech side of the same group kept its own registration and number — see AS5588. Two ASNs, one corporate history, and neither one inherits the other's shape: the Romanian AS is the local backbone, not a branch of the Czech one.
