Letter of Authorization (LOA) for IPv4 & BGP Operations
Get the authorization documentation required to announce, configure or operate authorized IPv4 resources with your network, upstream provider or data center.
Authorization for Network Resource Use
- Identifies the authorized organization
- Specifies the relevant IPv4 resources
- Supports network and provider coordination
- Prepared for legitimate operational use
What Is an LOA?
A Letter of Authorization (LOA) is a document used to confirm that an organization is authorized to use or request specific network resources or routing-related actions.
Depending on the deployment, an LOA may be requested by a data center, upstream provider, transit provider or another network operator before accepting an IP announcement, routing request or network configuration.
When You May Need an LOA
LOAs are commonly used when another network organization needs documented confirmation that you are authorized to use or announce specific resources.
BGP Announcements
Provide authorization when an upstream or network operator requires confirmation before accepting an IPv4 prefix announcement.
Data Center Deployment
Support IPv4 deployment when a hosting facility or data center requests documentation relating to the authorized network resources.
Upstream Coordination
Provide documentation required for coordination with transit providers, ISPs or other network partners involved in your deployment.
IPv4 Leasing
For eligible deployments, LOA documentation can support the authorized operational use and routing of leased IPv4 resources.
What an LOA Typically Includes
Exact requirements can vary between providers, but an LOA generally contains the information needed to identify the authorized party, resources and intended network operation.
Authorized Organization
The organization or network operator receiving authorization to use the relevant resources.
Network Resources
The IPv4 prefixes or other network resources covered by the authorization.
Operational Purpose
The network action, routing operation or deployment for which authorization is being provided.
Authorization Details
Supporting information required by the receiving provider to review and validate the request.

Letter of Authorization FAQ
Common questions about Letter of Authorization documents and their role in IPv4 and network operations.
What does LOA stand for?
LOA stands for Letter of Authorization. It is a document used to confirm that a party is authorized to perform or request specific actions involving network resources.
Why would my provider request an LOA?
A provider may request an LOA to confirm that you are authorized to use specific network resources or request a particular routing or network configuration.
Can Hyper ICT provide an LOA for leased IPv4 resources?
For eligible Hyper ICT IPv4 leasing deployments, the required Letter of Authorization can be provided where authorization documentation is needed by an upstream provider, data center or other network partner.
Can an LOA be used for BGP announcements?
An LOA may be requested as part of the authorization process before an upstream provider or other network operator accepts an IPv4 prefix announcement.
Is an LOA the same as an ROA?
No. An LOA is an authorization document used between organizations or network operators. An ROA is an RPKI object that authorizes an Autonomous System Number (ASN) to originate specific IP prefixes.
What information do you need from me?
Typically, we need information about the relevant network resources, the intended deployment and the organization or provider requesting the LOA.
