Part 1: IPv4 and IPv6 Implementations of DNS
The World Wide Web would be impossible to navigate without the addressing provided by the domain name system (DNS). DNS is also an important addressing method for LANs. Research the differences between the IPv4 and IPv6 implementations of DNS and compare those differences. What are the advantages of IPv6 DNS, and how will these advantages change how networks use DNS?
Based on your research, write a 3- to 5-page paper analyzing the differences between IPv4 and IPv6 implementations of DNS. Compare and contrast these differences. Discuss any advantages of using IPv6 DNS as compared to IPv4 DNS and discuss how those advantages may change the way that networks use DNS.
As part of the mastery requirements for this competency assessment, complete the following boldfaced item:
Write an additional 1–2 pages discussing the differences between IPSec and Network Address Translation when using IPv4 and IPv6.
Part 2: Comparing the Adoption and Implementation of Virtualization Versus Physical Server Infrastructure
According to Portnoy (2016), “Once the infrastructure services are virtualized and an organization starts to reap some of the fiscal benefits of their new strategy, an active program is put in place to move to the next level. As servers come off their leases, those workloads are migrated to the growing infrastructure. Companies usually adopt virtualization-first policies, which state that as new projects come in house, any server requirements will be satisfied by the virtual resources, rather than by paying for new physical resources. Actual hardware will be purchased only if it can be proven that the need cannot be satisfied with the virtual environment” (pp. 12–13).
Based on your research, write a 3- to 5-page paper that compares the adoption and implementation of virtualization versus physical server infrastructure. The paper should also discuss the costs and support considerations of the two technologies. Write as if to persuade the executive leadership of the company to invest in virtualization as a cost-effective option for managing the enterprise network.

Write an additional 1–2 pages discussing the difference between full virtualization and paravirtualization. Provide examples.
