Connectivity Internet

What is IP Transit and how does it work?

IP Transit is the foundation of global internet connectivity. It is a service in which an organisation allows its traffic to be routed through an internet provider’s backbone to reach the rest of the internet. While regular internet access is designed for consumers and small businesses, IP Transit offers a professional, scalable and high-performance form of connectivity for organisations with strict requirements around reliability, bandwidth and quality.

For companies operating in data centres, cloud environments or international markets, IP Transit is a critical part of their digital infrastructure. It enables worldwide reachability without depending on the variability of consumer-grade connections.

The technical fundamentals of IP Transit

IP Transit relies on the Border Gateway Protocol (BGP), the global routing protocol used to exchange traffic between autonomous systems. By using BGP, an organisation can:

  • make its IP ranges globally reachable
  • optimise inbound and outbound routing
  • create redundancy through multiple transit providers
  • influence routing policies based on cost or performance

IP Transit is typically delivered over a dedicated physical interface in a data centre, such as 1 Gbps, 10 Gbps or 100 Gbps ethernet. The customer receives access to the full global internet, including Tier-1 carriers and the provider’s peering ecosystem.

Benefits of IP Transit

1. Full Internet Reachability

Unlike limited peering or exchange-only setups, IP Transit offers access to the entire internet, ensuring any destination can be reached.

2. High Availability and Redundancy

Providers operate multiple uplinks, redundant routers and connections to Tier-1 carriers. Customers can further enhance redundancy by purchasing Transit from multiple providers.

3. Scalability

Capacity can grow from 100 Mbps to 100 Gbps or more. IP Transit scales seamlessly alongside business demands.

4. Low Latency and High Performance

Due to strategic routing and efficient peering, customers benefit from reduced latency, important for real-time services, hosting, gaming and cloud workloads.

Key considerations when selecting an IP Transit Provider

1. Geographical Coverage

For organisations active across Europe, the provider’s footprint, ideally in the Netherlands, Belgium and Germany, has a strong impact on performance.

2. Peering Policy and Network Quality

The number of direct peers, Tier-1 connections and the provider’s routing strategy all influence stability and speed.

3. SLAs and Support

Business-grade IP Transit typically includes 24×7 support and defined service levels for latency, uptime and packet loss.

4. Cost Model

Most IP Transit services are billed based on a committed data rate, often using 95th-percentile metering. Proper capacity planning prevents unnecessary costs.

IP Transit in Modern Hybrid and Cloud Architectures

Many organisations combine IP Transit with cloud interconnects, SD-WAN or edge technologies. In these environments, IP Transit serves as a reliable base for public internet access and global reachability, supporting the organisation’s broader networking strategy.

Conclusion

IP Transit remains a critical component of enterprise connectivity. It provides global reach, predictable routing and high performance. By selecting a provider with strong regional presence, solid peering relationships and transparent SLAs, organisations create a stable foundation for digital operations.
