| For anyone who has ever tried to visit a website, you might have noticed the small "keyword" string at the end of the URL, or the small box on the browser window that asks you to fill in some details about the domain name you want. However, even if you were given this unique key/string combination, it wouldn't make much difference to your web browser - the domain name you see is exactly the one you are supposed to see. This is because the name you are seeing is stored in a nameserver along with the IP address of the computer from which you requested the information. But what if you knew how to look up an IP address using your favorite browser? There are actually two ways of going about this: manually typing in the IP address or having a special program do it for you. Although both approaches have their advantages and disadvantages, it is better to use the one that comes with a hosting provider. The following paragraphs describe how these special nameservers work. DNS server software usually comes with its own program, called a DNS server. This program takes an IP address and creates a zone file, or zone database, that stores information about every domain in the Internet. The zone database stores such information as the names of the servers that host each domain, the names of any DNS server nodes that name any domain, and the names of any sub-domains, or DNS records. Every DNS server in the zone contains a copy of this zone file. You can ask your hosting provider to provide you with this zone file, or you can buy a program that will generate the zone files for you. In addition to a zone file, a domain name system also contains a number of other records. These records tell your computer which domain name servers are to be trusted, and which ones to avoid. For example, the dns security algorithm makes it possible for you to set up your computer so that it only asks for the latest certificate information from trusted domain name servers. If you have an old dns security certificate, you may not be able to connect to some websites. This prevents your IP address from being misused. There are two main types of dns security algorithm, or algorithms, used in DNS. One of them, known as the DNS Conferencing Protocol, or DNS Convention, allows you to establish inter-service communication between different servers on a network. This type of algorithm is used to determine which servers list the names of the other IP addresses that are connected to you. Another algorithm, known as the DNS Shared Security Key, or DNS Keylogger, lets you examine a zone's header to determine which IP address it corresponds to. To learn more about these two types of dns security algorithms, read "DNS Explained: What Every Webmaster Should Know" by Joe Sullivan. Some of the most commonly used dns service are to find the IP addresses of domain names, and to contact other domain names associated with that IP address. However, sometimes an IP address and a domain name are just too similar for it to be possible to distinguish between the two without performing manual research. There are two methods that can help you to determine the domain name associated with a particular IP address. One method uses'Traceable Name Lookup'and the other method uses Domain Name Tool (DNT). These tools use domain name lookups to search for information such as the owner of a domain, whether this domain name is still in use, and other details. However, both these methods can give conflicting results, as sometimes an IP address and a domain name are close enough to be interchangeable. An authoritative name server, or DNS server, is the server that authoritative documents are published to. The DNS database stores DNS queries and the answer that is returned from servers authoritative name servers. DNS servers maintain a record of zones, or address formats. Name resolution protocol also modifies these zones to prevent conflicting zone transfers and to ensure that zones are well-known and easy to understand. A reverse lookup using a domain name can be performed using a tld. This is done by typing the domain name or IP address of the domain name into the browser's address bar and clicking the 'enter' key. A resulting tld record containing the following information will be returned: tld-email, tld-service, tld-name, tld-ports, domain name, and interface. If you have any doubts, and especially if you don't know the difference between a domain name and a tld, you should contact your hosting provider and ask them. |
