A network manager that dynamically supplies and delegates equipment of clients with their IP addresses, standard portals and some other networking specifications, known as DHCP server.
- It depends on the standard operating procedure classified as Dynamic Host Configuration Protocol to answer to client-specific broadcasting commands.

At the end of this process, he'll have a clean document with Rob's recommendations and his original documents.
