List of Internet exchange points

List of Internet exchange points is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of Internet exchange points rather than just read about it. In short: This is a list of Internet exchange points (IXPs). There are several sources for IXP locations, including Packet Clearing House, who have maintained the earliest list of IXPs, with global coverage since 1994.

Key takeaways

List of Internet exchange points belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of Internet exchange points to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of Internet exchange points from memory before moving on to harder problems.

Reference excerpt

This is a list of Internet exchange points (IXPs). There are several sources for IXP locations, including Packet Clearing House, who have maintained the earliest list of IXPs, with global coverage since 1994. Also, Telegeography, PeeringDB and the Network Startup Resource Center. Additionally, there are Internet exchange point associations that publish lists of member IXPs. Some of the Internet exchange point associations are loosely grouped into the Internet Exchange Point Federation. For more information on the largest IXPs, see list of Internet exchange points by size.

Introduction The columns used in the lists below include the following information:

Region: The official Regional Internet registry (RIR) regions. Country: Uses ISO 3166-1 alpha-3 to display the country flag. City: A reference to a city article within Wikipedia. Name: Longname (Shortname). Entries flagged with an asterisk (*) do not appear in PeeringDB. IX-F region: IX-F region with which the IXP is associated.

Active Internet exchanges The IXPs in this list have a working webpage, are listed in PeeringDB, or both.

Africa

Asia

Europe

Latin America

Middle East

North America

Worked examples

Example 1 — a first encounter with List of Internet exchange points

Start with the simplest possible case. Write down what List of Internet exchange points claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of Internet exchange points before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of Internet exchange points ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of Internet exchange points

In research: List of Internet exchange points appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of Internet exchange points in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of Internet exchange points is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet-related lists, Internet exchange points, so understanding it makes those chapters shorter.
In everyday life: Look for List of Internet exchange points outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
