The hierarchical naming system for computers, known as the Domain Name System (DNS), in any source linked to the Internet or private network. This system connects diverse information with domain names assigned to each of the participants. More importantly, it communicates the domain names that humans understand into numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An analogy used often to explain the Domain Name System is that it is like a phone book for the Internet. It translates language a human can understand to computer hostnames into IP addresses. For instance, www.example.com changes to 192.0.32.10. DNS known also as a distributed database that offers mapping between IP addresses and Host names. Using the Domain Name System it is likely to assign domain names to sets of Internet users in an important way, free of each user's actual physical location. Since this is possible, World Wide Web (WWW) hyperlinks and Internet contact information will stay dependable and unbroken even if the existing Internet routing arrangements become altered or change, or the participant uses a mobile device. Internet domain names are easier to remember than IP addresses such as 209.75.188.166 (IPv4) or 2001:db8::1f70:6e8 (IPv6). Individuals take use this advantage when they talk about meaningful URLs and e-mail addresses without needing to understand how the computer will actually locate them. The Domain Name System allocates the accountability of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. Authoritative name servers are set to be responsible for their specific domains, and in turn can assign other authoritative name servers for their sub-domains. This mechanism has made the DNS distributed and fault tolerant and has helped avoid the need for a single central register to be continually
Company Alpha already has an existing DNS namespace. Different locations or organizations can be named with different subdomains such as nameone.corp.compan.com or nametwo.corp.company.com to ease administration. Make Active directory child domain immediately subordinate to their parent domain in the DNS name space. You can choose to create subdomains for organizations with in your company or location for example leveltwo.levelone.corp.company.com. These are a few things this company needs.
Company Alpha as all companies in my opinion should use a redundant DNS infrastructure. This will help with back up of the information in the system. With this being the age of information the ability to keep it safe and available is very important.
