What are multihoming assignments for?

Multihoming is the practice of maintaining more than one connection to the public Internet. Multihoming assignments are for small networks that are that currently multihomed, or plan to multihome.

Who is eligible?

An organization is eligible if it:

  • is currently multihomed, or
  • is currently using at least a /24 from its upstream provider and intends to be multihomed, or
  • intends to be multihomed, and advertise the prefixes within 6 months

I’m not multihomed yet, but I soon will be. Can I still apply?

Yes, if your organization intends to be multihomed and currently using at least a /24 from your upstream provider or plans to advertise the prefixes within 6 months.

What size are the assignments?

You can apply for an assignment of any size provided you can demonstrate a need for that space. To do this you should demonstrate that you will use 25% of the assignment immediately and 50% within one year.

The minimum size for an IPv4 assignment is a /24.

The minimum size for an IPv6 assignment is a /48.

This is an assignment not an allocation. What is the difference?

Allocated address space is address space that is distributed to Members for the purpose of subsequent distribution by them.

Assigned address space is address space that is distributed to a single end-user for the purpose of actual deployment in that end-user’s own network. Address space is also designated as assigned if the organization holding it uses it for the purposes of addressing their own network or applies it to a pool from which assignments are made dynamically as connections are established. Assignments are made for specific, documented purposes and should not be sub-allocated or sub-assigned.
