What is IP Transit?

Summary

This article explains the basics of IP transit and its importance in the modern internet. IP transit is a commercial service that enables internet traffic to travel to a desired destination by moving through multiple networks, which is often necessary for large bandwidth needs. When using IPv4 with IP transit, customers receive access to the global routing table which includes the prefixes of other customers of the upstream provider, prefixes advertised by ISP peers of the upstream provider, and prefixes received by upstream provider from its upstream providers. This article discusses the different types of broadband access available, including internet transit and dedicated internet access. It explains the different terms associated with these services, and provides examples of how they might be used.


IP Transit is an important component of the internet and it plays a crucial role in the successful communication between networks. It is a commercial service that enables internet traffic to travel to a desired destination by moving through multiple networks. This article is designed to give you a beginner’s guide to understanding IP transit and how it works.


IP transit is based on the TCP/IP stack which allows computers to talk to each other. All devices connected to the internet are identified by their respective Internet Protocol (IP) address. This address serves as a unique identifier for a device.



The internet consists three tiers of service providers.

  • Tier 1 providers, such as AT&T, CenturyLink, Zayo, and Verizon, have global reach and form the backbone of the internet. They can generally send data anywhere without having to pay transit fees.
  • Tier 2 providers have very large networks with a wide global presence while
  • Tier 3 providers are typically without any transit customers and have no peering connections.


IP transit is a paid service whose price is determined by bandwidth usage. The role of a transit provider is to connect a customer’s network or downstream ISP to the global internet. To do this, the transit provider allows the customer traffic to pass through its network so that it can reach all possible destinations on the internet. Customers receive a full BGP Internet table that includes prefixes of other customers of the upstream provider, prefixes advertised by ISP peers of the upstream provider, and prefixes received by upstream provider from its upstream providers.

Using IPv4 addresses with internet transit services is still common and widespread. IPv4 is the fourth version of the Internet Protocol and it is used to identify devices on a network using IP addresses. IPv4 provides a unique 32-bit address space allowing for 232 (or 4.3 billion) possible addresses.

When using IPv4 with internet transit services, customers receive access to the global routing table which includes the prefixes of other customers of the upstream provider, prefixes advertised by ISP peers of the upstream provider, and prefixes received by upstream provider from its upstream providers. The traffic coming from the internet and destined to the customer is known as “going downstream”, while traffic from the lower-tier ISP to a higher-tier provider is called going upstream.

When it comes to IP transit, there are two main types: IP transit and IX transit. IP transit is when one party pays another for access to a network (and the networks connected to it).

IX transit is an interconnection of multiple networks at a single physical location in order to facilitate the exchange of traffic.

The third type of transit is called DIA (Dedicated Internet Access), which provides direct access to the internet. Unlike IP transit, DIA offers more issues with latency and is not suitable for larger bandwidth needs.
