Your assignment is to prepare and submit a paper on network infrastructure for segments within the enterprise. However, for addressing the requirement of establishing zones on an external DNS server, only one domain will be configured, i.e., woodgrove.com, as it is the only domain that maintains and holds external records. Moreover, a replica of the domain DNS zone will be maintained at every hub site. However, each domain's leading hub site will keep an image of DNS zones of other parts.

For every domain on the computer network, there is also a requirement of configuring a local zone, as it will sanction the configuration of secure and dynamic updates. Likewise, Microsoft Active directory has an embedded default functionality of replicating integrated zones to all the domain controllers within the same domain (Jones & Rose, 2003). As every instance is playing the role of a primary zone, all the available domain controllers are granted for dynamic updates.

IP/DHCP Scheme

Furthermore, the justified cost and the appropriate use of technical excellence, network configuration, network products, security appliances, applications, and support will deliver value to the organization. For ensuring business continuity, redundant data connectivity links, and alternate configurations are performed within each connectivity hub for addressing network service downtimes. Next-generation network (NGN) supported hardware is considered for ensuring significant cost savings for addressing network scalability. Therefore, stakeholders can trust us for value delivery and better Return on Investment (ROI) for the budgeted amount due to all these benefits.

For the convenient use of IP addressing, we will use a 10.0.0.0/8 subnet for this scenario, as it will provide the required allocation of IPv4 addressing. However, we will assign a class C subnet mask for remote offices or branches, as there is no requirement of allocating so many IP addresses at branches. The subnet mask for a class C network will be 255.255.255.0. Moreover, we will give a class B subnet for hub branches, as they need IP addresses for internal use and the components that connect to the hub branches. The class B network address will be 255.255.0.0.

Furthermore, for allocating subnet masks for branches in New York, Miami, and Toronto, we will perform subnetting that will distribute the adequate size of address spaces required and, at the same time, give room for network expansion options in the future.&nbsp.
