6. Understanding of ARIN’s role in the Internet governance ecosystem

a) What is ARIN’s role in the Internet governance ecosystem?

ARIN is one of five global Internet registries and a member of the Number Resource Organization (NRO).

This includes technical and policy aspects that interface with ICANN, other RIRs, the United States Government, and the Internet community globally.

Chair of the accountability task force for the RIPE Community, Co-chair of the Database Working Group for the RIPE Community.

7. Board Discussion Topics

a) Risk Oversight and Management

i) Understanding and overseeing organizational and environmental risk is an important responsibility of Trustees. What do you see as potential risks to the organization, and which are newer risks that have emerged more recently?

Risks of the legal situation with AFRINIC, the RIR/NRO commitments to support other RIRs financially could become a burden upon ARIN and other registries were this legal situation be determined that AFRINIC has certain liability. The security and stability of the system is dependent upon all RIRs to be rational and financially stable. Governance of the Internet including sanctions like the situation in Ukraine and it’s impacts against Russia. This is also relevant for other sanctioned countries. Elements of Internet governance that might include multiple State actors, the ITU/United Nations, and other governing bodies that might attempt to influence the ARIN community and organization.

ii) How should the Board best discharge its responsibilities regarding risk oversight and management?

The Board should establish a risk matrix. This would include identifying strategic, financial, and governance risks. These risks would either be managed within relevant committees of the board or within the main board directly. The purpose would be to identify and manage any risks that could materially impact the operations of the organization or otherwise threaten the sustainability of the organization.

iii) How will you contribute to strengthening risk oversight and management at ARIN?

 I would propose conservative methods to identify, inventory, and regularly review risks. To appropriately take action to protect the organization or proactively resolve risks with a specific method to measure and manage all organizational risks.

b) Strategy

i) Supporting and reviewing the strategic direction identified by ARIN’s management, in consultation with its membership, is an important responsibility of Trustees. Based on your understanding of ARIN’s current strategic plan and the environment in which it operates, what opportunities or challenges do you foresee for the organization?

The organization continues to see number blocks transfered to other RIRs, some of the transfers are the result of unfavorable legal terms or other issues that companies choose to manage their resource in other regions. I see that the legal and technical frameworks need to provide value for companies to keep their resource in the ARIN registry this includes RPKI, Registration Service Agreements, and overall services. This is essential to maintain the stability of the organization and the financial health for the future.

ii) How might these challenges and opportunities influence current or future strategic plans?

These issues will require a detailed review of services, pricing, and legal terms to best meet the needs of the organizations membership and the global Internet community. Many of these will require difficult discussions to manage risk, sustain financial health, and provide industry leadership to maintain the organization into the future.

iii) Please explain how your background and experience would help in addressing what you believe are ARIN’s greatest challenges.

I have a clear understanding of where the organization has come from, where the organization is today, and a reasonable understanding of the direction the organization is headed in the future. With my extensive industry experience, I believe I can support the Board and the membership to identify and manage the organizations greatest challenges. This will include a solid understanding the business, legal, and technical landscape and providing the feedback and leadership to navigate all issues facing the organization.
