What is LOA (Letter of Authorization)?
The Letter of Authorization (LOA) is a formal document issued to a client after successfully completing the Assignment Request process. This document grants the client permission to announce an ASN (Autonomous System Number) for a specified IP address range.
The LOA serves as proof that the client has the right to broadcast and manage the assigned IP address range within a network. It is often required by data centers, internet service providers, and network operators to confirm that the client is authorized to use the specified resources.
The document typically includes the following details:
- Client’s name and contact information
- Assigned IP address range
- ASN details
- Authorization date
- Issuing organization’s contact information
This document ensures proper routing and compliance within global network infrastructures, preventing unauthorized use of IP address space.
