MIX - Milan Internet eXchange

  • Internet eXchange (IXP), founded in 2000
  • The leading Italian Internet eXchange is among the first in Europe in terms of traffic received
  • Point of “multiple interconnection” to which the networks of Internet operators in Italy (ISPs, carriers, content providers, hoster …), both national or otherwise, connect to exchange IP traffic (peering) with each other, efficiently and at convenient costs.
  • One of the few European Internet Exchanges (IXP) equipped with its own data centre
  • 8 PoP: 7 in Lombardy and 1 in Carini (Palermo)
  • Founding member of Euro-IX, the international association of IXPs
  • Founding member of Open Hub Med, the first neutral HUB in Italy for the interconnection of the networks in the Mediterranean Basin and Northern Europe
  • Certified for its high standards of reliability and security 
  • Since 2018, joining MANRS (Mutually Agreed Norms for Routing Security), the global initiative to reduce the most common routing threats.


1994 - First NAP in Italy founded

The first Italian NAP was set up in a Lombard inter-university consortium in 1994 and, shortly thereafter, a second one was established in Rome in a similar consortium. It is no coincidence that both NAPs were located on academic grounds: the need for neutral terrain in which no areas of competition are created between the individual members is a feature that distinguishes all internet exchange points in the world (many of which are still hosted in public facilities, typically in research centres and universities).

1996 - ``mix`` founded

In the early 1990s, the campus in via Caldera, in the North-West area of Milan, began to host an increasing number of ISPs until currently becoming the most important catchment area for Internet network operators in Italy. The large concentration of ISPs in the campus, therefore, was a favourable ground for the creation of a NAP and so, in 1996, a volunteer and non-profit initiative within the campus, gave rise to a new NAP in Milan, the first “mix” (the term “mix” at the time implied the IX service, and there was no mention of MIX as a company).

2000 - MIX S.r.l. founded

Over the years, the ease of connection achievable on campus was a factor determined by the increased presence of operators in the “mix” compared to the first Milanese NAP which continued to exit but could no longer evolve.

This led to the issue that the “mix”, took on such proportions and with an extremely high volume of peering traffic, which required both internal regulation, which included the specifications of the levels of service necessary for its proper functioning, and of a host physical structure tailored to it.

Hence the birth of MIX S.r.l. (January 27, 2000) in which the majority of operators who contributed to the creation and development of “mix” participate as members, in order to guarantee neutrality and functionality.

Such a structure fits well into the Italian Internet reality and improves its use by making available to all ISPs, both national and foreign, a reliable band and at high speed that allows the management of traffic dedicated also to multimedia applications without any downgrading and certainly, represents a point of expansion towards Europe for the realization and increase of such applications.

2001 - EURO-IX founded

In 2001, seven European IXPs, including MIX, promoted the foundation of EURO-IX, the European Internet Exchange Association, whose aim is coordination, exchange of knowledge and experience, and the development of harmonization activities among IX of the different countries for the benefit of the entire European Internet community.

2015 - Open Hub Med launched

On November 23, 2015 the consortium Open Hub Med, neutral and open point to all internet exchange operators was launched in the Italtel site of Carini (PA): MIX is a founding partner.

The Sicilian hub aimed to become the natural collector for the 135,000 km of submarine cables that currently land in Sicily and to reconstitute the ecosystem of Milan Caldera, thanks to the presence of MIX. Open Hub Med is not just a landing station, but intends to play a strategic role as a privileged route for traffic coming from Asia, the Middle East and Africa and heading towards Northern Europe, thus relaunching Italy’s role in international telecommunications.

2015 - OIX-1 certification of Open-IX

MIX obtained the OIX-1 certification of Open-IX (released for only 5 IXPs worldwide) confirming the level of excellence in terms of security and reliability of services.

2017 - ISO27001:2013 certification

MIX is the first Italian IXP to overcome the strict controls envisaged by the ISO27001:2013 certification, which covers all the security aspects of IT installations and processes.

2018 - Free share capital increase to 1 Million

On April 24, 2018 the Shareholders’ Meeting of MIX srl resolved a free share capital increase from euro 99,000.00 (ninety-nine thousand) to euro 1,000,000.00 (one million), by transferring to a corresponding part of the share capital available reserves of the company entered in the balance sheet. The initiative was made possible thanks to the steady growth that the Company has recorded over the years, the result of major investments, aimed at the development of the Italian portion of the Internet.

2018 - MANRS subscription

MIX has always been aware of the security problems that threaten the functioning of the Internet every day, and implements actions to counteract them: this is why has joined MANRS – Mutually Agreed Norms for Routing Security, the initiative supported by ISOC which promotes the adoption of a series of technical measures to make the global routing infrastructure more robust and secure.

2020 - MIX turns twenty

MIX operates as a “multiple interconnection” point to which the networks of over 300 Internet operators (ISPs, carriers, content providers, hosters) are connected to peer efficiently and at advantageous costs. At the beginning of 2020, the traffic exchanged exceeds a Tbps but a more than six times greater transmission bandwidth is available, which allows the exchange of Internet traffic for multimedia applications without any loss of performance.
