How resources flow

  1. System Admin

    Creates top-level pools and AS blocks — the role IANA plays on the Internet.

  2. RIR

    Regional registry. Allocates large blocks and AS numbers to its LIRs.

  3. LIR

    Usually an ISP. Splits allocations and assigns space to customers.

  4. End User

    Runs its own network, originates routes and chooses its peers.
