| In previous article, we discussed on how to configure gliederung einf hrung domain name system domain, the e-mail account, the IP address and registration of the domain name. In this article, we talk about the DNS server, or domain name server. It is also called DNS server or domain name server. There are different types of DNS servers, each of them having its own role in domain name system. The most popular type is the C class IP addresses. The major role of these is to translate the request that comes from the client for accessing a web site. The response from the server is then sent back to the client to access the pages of the web site. In other words, the C class IP addresses are used for translating the request for the domain name system to a readable and relevant reply. Then, there is the C class IIDs. These are used by the client computers and client-directed protocols for DNS resourcing. Then, there are the delegated labels or domain names. These are normally IP addresses assigned by the delegated administrator of the domain name system. This system manages the global suffix extensions and the local area network (LAN) addresses. The domain name system actually consists of two parts: the delegated domain name infrastructure (DUNI), which is a set of computer resources including the routers and their support devices; and the delegated ressource eines ressource. The first part of the system refers to the devices and networks on which the DNS servers and programs function. In the second part, the DNS service can access the information from these routers and delegated units. This is the domain name service or the DNS resolution service. In the previous article about IP address, the term 'iterative abfrage' referred only to the normal ABR processes. The process in this article is slightly modified so as to make it more useful in IP address management. The word 'iterative' is introduced to correspond to a process that has multiple stages and therefore the domain name may be considered as a domain-name object or source. The domain name used for the source may contain one or more alphanumeric characters. These characters are used to represent the IP address of the source. The process called resolve resolves an IP address or domain name. The resolved domain name encodes a domain name of an IP host or domain name of an autonomous system number. An IP host is a collection of computers. An autonomous system number is a set of computers controlled by an organization to resolve domain names resolved from IP addresses. It also stores information about DNS servers that are listed in its directory. To have a domain name resolved, the client computer contacts the DNS server and requests a name of the domain name it wants. The DNS server searches the databases for information about domain names and then returns a list of all the domains that are associated with an IP address or that match a specified domain name. After finding a match, the server identifies the domain name to be used and adds it to the zone files. This process is repeated until there is a satisfied client. In order to have a domain resolved, the client computer contacts an IP-based DNS server and has its name registered. The server looks up the IP address of the name and finds a corresponding name in its zone database. Then it stores the name in its zone database. When a query is sent to the server, it checks the zones to find the name that it already has in its zone database. If it finds the name already in the database, it will return a response that enables the client to use that name to reach the desired destination. |
