IP Transit

Carrier-grade Internet connectivity for networks that need to reach the global Internet through routing handoffs, including redundant designs.

What it means

IP Transit is Internet connectivity sold to networks, carriers, content providers, and large operators. It usually pairs with BGP so the customer can exchange routes, control outbound path selection, and influence inbound paths under its own routing policy. Redundant IP Transit can be built as a second handoff, a transported IP Transit circuit, diverse transport into an interconnection point, or two separate IP Transit providers.

Where it fits

  • Networks with their own ASN
  • Content, hosting, carrier, and enterprise networks
  • Multi-homed Internet designs
  • Redundant transported IP Transit
  • Two-transit BGP designs
  • Customers that need route filtering, communities, and higher-capacity handoffs

What we'll talk through with you

  • Do you have an ASN and IP space?
  • Do you need full routes, default route, or partial routes?
  • What port speed and commit level do you need?
  • Do you need one IP Transit, a backup handoff, transported IP Transit, or two IP Transit providers?
  • Do you need IPv4, IPv6, or both?
  • Should this connect at a Quad State Internet location or another interconnection point?
Important context IP Transit is different from ordinary business Internet. Redundancy also has to be designed: two circuits may still share a lateral, transport route, building entrance, cross-connect point, or upstream path if nobody reviews it.

How it shows up in a real project

A regional provider brings a 100G handoff into a Quad State Internet interconnection point and uses BGP to exchange routes for its own customers. If the provider needs resilience, Quad State Internet can also scope a redundant transported IP Transit circuit or a two-transit BGP design.

Learn the goal

We start by translating the business need into endpoints, capacity, term, resiliency, and support expectations.

Map the meet points

We identify carrier meet points, IX ports, cloud on-ramps, colocation footprints, or private handoffs that matter.

Choose the model

The answer may be DIA, IP Transit, Type II access, dark fiber, wavelength, IRU, managed transport, or a blend.

Build the path

Quad State Internet can build, coordinate, light, monitor, document, and support the route after turn-up.

Related things to learn

ASN An Autonomous System Number identifies a network that controls its own routing policy. BGP The routing language networks use to tell each other where traffic should go. Carrier Handoff / NNI The physical and logical place where Quad State Internet connects with another network or carrier. Interconnection Points Places where networks meet to exchange traffic, buy transit, reach cloud platforms, or connect private paths.
