    # The address-pools section lists the IP addresses that MetalLB is
    # allowed to allocate, along with settings for how to advertise
    # those addresses over BGP once assigned. You can have as many
    # address pools as you want.
    address-pools:
    - # A name for the address pool. Services can request allocation
      # from a specific address pool using this name, by listing this
      # name under the 'metallb.universe.tf/address-pool' annotation.
      name: default
      # Protocol can be used to select how the announcement is done.
      # Supported values are bgp and layer2.

      # A list of IP address ranges over which MetalLB has
      # authority. You can list multiple ranges in a single pool, they
      # will all share the same settings. Each range can be either a
      # CIDR prefix, or an explicit start-end range of IPs.
