インターネットエクスチェンジ
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, Telegeography, PeeringDB and the Network Startup Resource Center. Additionally, there are Internet exchange point associations that publish lists of member IXPs. The Internet exchange point associations are loosely grouped into the Internet Exchange Point Federation.
