AS57358 — Our Autonomous System
Since August 2023, we have operated our own network under the autonomous system number AS57358. This gives us full control over our routing infrastructure – and allows us to offer our customers highly available, individual connectivity solutions from a single source.
Our own autonomous system since 2023
An autonomous system (AS) is the foundation for independent, self-determined routing on the internet. With AS57358, IMT-Systems has operated its own AS since August 2023, with its own provider-independent IPv4 and IPv6 address space.
This sets us apart from many hosting providers that merely pass on IP addresses from their upstream provider. With us, full control over routing remains in our hands – including path selection, peering strategy and the response to incidents.
Highly available routing architecture
Our network is consistently designed for resilience:
- Two highly available core routers at our location at Digital Realty (Interxion) FRA15 in Frankfurt am Main
- BGP multihoming across multiple upstream carriers with automatic failover
- Spine-leaf architecture based on Dell switches with 100 GbE connectivity
- Redundant fiber feeds via physically separated routes
- Own IPv4 and IPv6 networks – portable and independent of a single upstream
Direct carrier and DE-CIX connectivity
Through direct connections to top carriers such as Plus.line AG and Cogent Communications, as well as our connection to the DE-CIX – Germany’s largest internet exchange point – we guarantee extremely low latencies and high-performance connectivity to the global internet.
The proximity to the DE-CIX and the location on the Digital Realty campus in Frankfurt’s Ostend district mean the shortest paths to more than 700 carriers, ISPs, CDNs and internet exchange providers.
Secure routing with RPKI
Security begins in routing. Our prefixes are RPKI-validated (Resource Public Key Infrastructure), allowing us to effectively prevent route hijacking and accidental misannouncements. Combined with a carefully maintained routing architecture, AS57358 offers the stability and security that business-critical applications require.
IP transit and internet access on the Digital Realty campus
With AS57358, we provide first-class connectivity not only to our own cloud and server customers – we also make our network infrastructure available to other companies on the Digital Realty campus.
If you operate your own hardware at Digital Realty FRA15 or wish to migrate there, we offer you:
- IP transit with redundant, high-performance connectivity to the global internet
- IPv4 and IPv6 addresses from our address space
- BGP sessions for your own autonomous system – ideal for multihoming
- Scalable bandwidth – from single gigabit connections to high-capacity solutions
- Short paths thanks to shared presence in the same data center
- A dedicated contact person and transparent SLAs
This way, you benefit from the same carrier connectivity, RPKI security and routing quality that our own services are built on – without having to build your own autonomous system or negotiate carrier contracts.
