The Department of Science and Technology (DOST) - Advanced Science and Technology Institute (ASTI) established the Philippine Open Internet Exchange (PHOpenIX) as a neutral and non-commercial Internet Exchange that will encourage local telecommunication companies and other data service providers to interconnect ("peer") their networks.

Recently, a concern was raised about the IP addresses that the DOST-ASTI advertises to its partners in the PHOpenIX. The DOST-ASTI clarifies that its entire IP address block (202.90.128.0/19) is being provided and advertised to all peering partners; and that information about this address block was already available to all its partners in 2016 as part of the peering contracts or membership agreement documents.In specific reference to the site "mirror.pregi.net", it should be noted that IPv4 address of this site is embedded or subsumed within the IP block 202.90.128.0/19. Consequently, the contents of "mirror.pregi.net" have always been accessible through the more direct peering route to the partners. This implementation, where individual addresses within advertised blocks are not required to be further white-listed downstream, is consistent with modern peering and network prefix routing advertisement practices worldwide.

DOST-ASTI would like to assure the general public and its partners of its commitment to establishing and sustaining an open, inclusive and robust Internet Exchange that promotes the benefits of the Internet for Filipinos. This statement is issued in the spirit of transparency, which has guided and continues to define the philosophy and practice of the DOST-ASTI in the implementation of PHOpenIX.

The Advanced Science and Technology Institute (ASTI)

Established in 1987 by virtue of Executive Order No. 128, the Advanced Science and Technology Institute (ASTI) is an agency of the Department of Science and Technology (DOST) mandated to undertake research and development activities in the advanced fields of information and communication technology and electronics. Since the 1990s, the DOST-ASTI has undertaken numerous projects in network technologies and high performance computing, including pioneering efforts in open source software, IPv6, VoIP and establishing a local Internet exchange and a globally-connected research and education network. ASTI-developed products ranging from electronic data acquisition, embedded and enterprise software, biomedical devices and environmental monitoring systems have been successfully deployed - supporting nationwide initiatives in public health, e-governance, education and disaster risk management - including the underlying nationwide infrastructure of over 1,500 sensors and weather stations for Project Noah. Recently, the DOST-ASTI launched a multi-mission ground control station for multiple satellites, including the Philippines' first microsatellite, Diwata-1. The DOST-ASTI celebrates 30 years of ICT and microelectronics R&D and innovation in 2017 and continues to dedicate itself to delivering technology solutions in support of a productive and resilient Filipino society.

About Us

Over the years, the emergence of information and communications technology has greatly affected the lives of people in the world crossing borders among countries and bringing access closer to one another. In the same token, the birth of Microelectronics has resulted to progress in the development of smaller, lighter and more efficient electronic devices.

This development has a striking resemblance to the birth of one of the research and development institutes of the Department of Science and Technology (DOST) – the Advanced Science and Technology Institute (ASTI). It was in 1987 when President Corazon C. Aquino renamed the then National Science and Technology Authority (NSTA) to Department of Science and Technology (DOST). As an offshoot of such sequential events, the DOST-ASTI was created as a research and development institute of the Department by virtue of Executive Order No. 128.
