'''IXP''' means Internet Exchange Point. It is also known as Network Access Point or NAP. An IXP is a physical point where different [[ISP]]s meet to exchange their data and hence different networks are connected together to form the Internet. IXPs are perhaps the most important part of internet without which the concept of global wide area networking is not possible.<ref>[http://www.infocellar.com/networks/internet/nap-ixp.htm InfoCellar]</ref>

There are 91 countries with 1 or more IXPs. However 106 countries of the world depend on others for data transfer and need to develop their own IXPs.<ref>[https://prefix.pch.net/applications/ixpdir/summary/ PCH Prefix]</ref> You can see the list of all the IXPs present in the world [http://www.datacentermap.com/ixps.html DataCenterMap here].
