| When you're about to go to a website and type in a domain name, you probably expect to see a page that has a Web address, or domain name, followed by the IP address. That's the way it usually is. But if you're like most users, that's not what happens. Instead, what usually happens is that the browser looks up the IP address, and comes up with a confusing page. Here's why that happens. Most browsers support a standard query language (SQL) that allows it to look up domain name system information. However, not all browsers have the same functionality for DNS lookups. Some just use the IP address as a primary key in its database, and some don't even have a built in DNS storage system. That's where the DNS Services come in. The DNS service can help you get the IP address from any DNS server, whether it's a name domain name system or a ressource. The DNS service is built on top of the NSLookup and Name Server Routing protocols. This makes it possible for users of Microsoft's Active Directory to use their DNS infrastructure to access IP addresses and DNS records. For example, when a user types in an IP address in the browser, the DNS ressource that Microsoft provides updates the DNS server with the necessary information. Once that happens, the user can get a record from the DNS server that contains the IP address and the name domain that matches it. The way this works is that the DNS server looks up the IP address that the client entered and searches the domain name tables for any name that is physically near the IP address. If there are multiple names that are near the IP, the DNS server searches them all. If a match is found, the DNS service retrieves the record and passes it on to the client for further processing. If the DNS service cannot retrieve the data from one of the DNS servers, the client will receive an error message. In this example, the domain name used is "com." Next, the "gliederung einf hrung domain name system domainnamen und die dns-hierarchie" in combination with "rs" and "c" are used for the keyword "domain name". It can be concluded that "com." is not an allowed keyword because it is an extension. In the previous example, the second step is to register the domain name that was originally typed in using the USER command. The first step in the registration process is the creation of a service-based TLD or top-level domain. Then, the domain name is registered with an ICANN or International Certificate Organization. Registration is done in accordance with the name that was typed in during the registration process. In this case, the domain name has been typed in as cmyk(dot) com. For the second step, we have to check the IP address of the domain name. The process in this case is again same as in the previous example but the implementation differs by the provider. In the first step, we need to obtain the resolved IP addresses of the domain name. For the second step, the IP addresses of the domain name are resolved using the iterative abfrage algorithm. Finally, the third step uses the IP address data obtained in the previous steps to derive the C zone name and other required data. The process is again same as the previous one but now for the ACK from DNS server. For the last step, the DNS server processes the ACK from the ressource and updates the zones with the new ones. As the DNS zone updates are performed, you should be able to ping all your clients. The ping needs to send the acknowledgment to all the servers which results in theircknowledging the ACK from your ressource. |
