How Will Address Space be Assigned to Networks?

       Why addressing is an architectural issue
          Addresses are a limited resource
          It might take a long time to get more
          Re-addressing can be painful
        (Though some networks more painful than others)
        Consider interplay of entrance selection and addressing
        Don't split anything smaller than a /24 across sites
        (Except for point-to-point links)
        Consider using IP unnumbered on point-to-point links
        Consider host routes for loopback interfaces
        Think about the sites where you now have Internet connections
