    CK is globally known in both, the I-Star and the RIR world and an active contributor to the global Internet community over the last two decades.
    His understanding of the technical as well as policy and governance world are very valuable for the ICANN community, I therefore strongly recommend him for Seat 10.

  2. Christian has held many community positions in the industry. Most recently I experienced him as the Chair of the RIPE NCC Executive Board. He is an excellent chair and understands the role and responsibilities of a Board very well. Christian is good at guiding and leading a discussion and coming to a conclusion. With his leadership qualities and his understanding of the Internet industry, he would be very suitable as an ICANN Board member.

  3. Salam Yamout says:

    Christian is a seasoned leader, able to listen and bring different stakeholders to consensus. He understands very well the numbers and protocols aspects, and the relationships between the different Internet Governance constituencies. Finally, Christian cares about the Open Internet and has given substantial amount of his time in the last 12 years volunteering in various organizations.

    I strongly recommend Christian as a candidate for board seat 10.

  4. Christian would make an excellent ICANN board member. He’s an accomplished representative of the Internet operations community, and would bring a deep understanding of the numbers and protocols aspects of ICANN’s responsibilities to the ICANN board. As well, he’s a veteran of many Internet governance roles, and understands the circles within which ICANN operates, between the people who keep the Internet working, and the governments that regulate it in the public interest.

    I strongly recommend Christian as a candidate for board seat 10.
