Board Members

Hans Petter Holen

Hans Petter Holen has been actively involved in RIPE and the Internet industry for over 20 years. His extensive first-hand knowledge of global IP address policy creation comes from his time as Chair of the RIPE Address Policy Working Group (formerly known as the Local Internet Registry Working Group).

Previously a member of the NRO Number Council, Hans Petter has also been part of ICANN’s ASO Address Council since its formation in 1999 until 2013, with ten years as Chair and Co-chair.

Hans Petter graduated from The University of Oslo in 1988 with a Bachelor’s Degree in Computer Science. He continued with further studies there while working on administering the Norwegian EuNet node at the University. He was among the founders of Oslonett AS, one of Norway’s first commercial ISPs, and has worked for various other LIRs. Hans Petter joined Visma in 2004 - first as IT Director and then as Chief Information Security Officer (since 2015), where he employs his extensive knowledge of the design, implementation and operation of Internet services and networks in a secure manner.

Hans Petter Holen was appointed RIPE Chair at RIPE 68 on 16 May 2014.

Nigel Titley

Nigel Titley graduated from Oxford University in Engineering Science and Economics, more years ago than he cares to remember. Upon his graduation, Nigel started work at British Telecom's research labs, where he worked for a number of years on different projects, eventually gravitating towards the new-fangled Internet protocol in the late 1980s. He played a part in the Internet's introduction to the UK and Europe, by arranging for BT to be a substantial player in the early days and by designing and operating the first (unofficial) BT email relay, shifting email between BT's internal systems and the Internet.

After helping to design and operate BT's first commercial Internet service, he left to design and oversee the applications services (DNS, email, NTP and Usenet news) in Level 3's new European network. The advent of ethernet over IP led to his becoming one of the founders of PacketExchange, a company which set out to exploit the technology.

From there, he went on to become Peering Manager for FLAG Telecom and then finally to Easynet, where he remained until early 2014. His current job involves the development of his long-time small business designing and selling environmental logging equipment and specialist electronic components. On his journey, Nigel found time to help found the London InterNet eXchange (LINX) and serve on its board for 12 years, to found Nominet (the UK registry), to act as co-chair for the RIPE Database Working Group, to launch 6UK (an organisation dedicated to encouraging IPv6 use by businesses in the UK) and, of course, to serve on the RIPE NCC Executive Board, of which he is currently the Chairman and which takes roughly two days a week of his time. Nigel has been active in the RIPE community for many years, having co-authored a number of policy proposals related to transfer policy, fair run-out, certification, and recovery and re-use of IPv4 resources.

As Nigel is now effectively his own boss, he is able to dedicate whatever time he feels appropriate to serving the Internet community and he intends to continue to help in whatever way he can.
