|A domain name is a word or string of letters and/or numbers that identify a specific, unique computer unit. Domain names are most commonly used in the world of web hosting and domain name registration. Domains are used to tell servers what specific unit or computer is being identified. There are three types of domain names, also known as top-level domains (TLDs), generic domains, and country-specific domains. Domain names can also be generic top-level domain names that point to foreign countries or continents.|
Domain Name System (Dns) is a hierarchical, associative naming scheme based on a global, publicly accessible database for computers, networks, or any peripheral device connected to the Internet. The DNS system translates domain names into numerical IP addresses that are then used to access websites. In essence, DNS serves as a phone book for the Internet. Many organizations, companies, and individuals utilize domain names as an effective tool for domain name registration, domain name management, and maintenance.
A DNS server is usually web-based and connects clients via the Internet to different domain registrars. These clients can either consult domain registrar databases or request domain name records from DNS servers. A DNS server can provide information about nameservers and query records, as well as obtain other related data. In addition, DNS servers can also provide security and authentication services.
To obtain the IP address of a domain name, a client can perform an IP address look up, domain name reverse lookup, or IP address lookup using a DNS server. A DNS server returns a pair of IP addresses or TLDs as defined by the nameservers listed in its database. A client can use an IP address lookup to check whether a domain name is owned by a company, private individual, or public entity. An IP address can be accessed by typing the domain name into a browser.
If a domain name is not available through a DNS server, clients can search for it using an authoritative dns server. The authoritative dns server is responsible for maintaining DNS records and all associated subnets. If a domain name requested is not found in the directory, the client can opt to get the requested domain via an IP address, a Nameserver or the hostname extension.
Using an IP address to obtain domain information is commonly referred to as an IP to Domain look up or an IP to host name (IX DHCP). This type of lookup requires a web browser and the program necessary to translate domain names and IP addresses into IP addresses. Two common tools for performing this type of lookup are the Google Webworm and ICQ. Some reverse dns lookup servers also support ICQ. The Webworm uses ICQ's own technology to determine the IP address of a domain.
An IP address is simply a string of numbers and letters which uniquely identify a domain. IPs are mapped onto domain names in a network infrastructure. This mapping process is called domain name translation (or domain name translation). Domain names themselves carry with them an IP address that is unique to each name. To get the IP address of a domain name, a reverse DNS server searches for the IP record found in the DNS database.
When performing an IP to domain lookup operation, a reverse dns lookup server searches the DNS database looking for an IP record matching the domain name in question. Once the query is returned, the reverse dns lookup service parses the returned domain name string and creates the IP address associated with the domain name. Then, using the appropriate settings, the dns record is sent back to the client computer system. The client's computer then directly connects to this dns record and performs the requested operation, as if the domain name were just one listed in the phone book.
