to the ISP, retaining two for ISP connectivity. In addition, it allows for the parallel in-
frastructure to be built prior to migrating users to the new network.
With private addresses, the hospital can choose to use 172.16.0.0/16 for private ad-
dressing. The addressing scheme shown in Table 16-2 provides sufficient address
space for each network.

Another solution is to retain the public addresses and use them in the internal net-
work. This solution is less preferred than private addressing. Table 16-3 shows the rec-
